Jack Ü
Jack Ü was an American electronic dance music duo consisting of producers and DJs Skrillex (Sonny Moore) and Diplo (Thomas Wesley Pentz), formed in 2013 as a collaborative side project to explore experimental sounds blending dubstep, moombahton, and pop elements.[1][2] The duo made their performance debut at Mad Decent Block Party in 2013 and released their first single, "Take Ü There" featuring Kiesza, in October 2014.[3] Their only studio album, Skrillex and Diplo Present Jack Ü, dropped unexpectedly on February 27, 2015, during a 24-hour DJ set streamed online, and includes high-profile collaborations with Justin Bieber on "Where Are Ü Now," Missy Elliott and Aloe Blacc on "Get Free," and Kai on "Mind."[4][1] The album peaked at number 26 on the Billboard 200 and was certified gold by the RIAA in 2016 for sales exceeding 500,000 units in the United States.[5] "Where Are Ü Now" became their biggest hit, reaching number 8 on the Billboard Hot 100 and topping dance charts worldwide.[1] At the 58th Annual Grammy Awards in 2016, Jack Ü won Best Dance/Electronic Album for their self-titled release and Best Dance Recording for "Where Are Ü Now," marking Diplo's first Grammy wins and Skrillex's additional honors in the electronic category.[6][7] The project has remained largely dormant since, though the duo performed select sets, including closing Ultra Music Festival in 2015 and a Grammy live rendition of "Where Are Ü Now" with Bieber; in 2025, they revealed a completed second album featuring Florence + the Machine and Charli XCX that may never see release.[8][2]Background
Members
Jack Ü is composed of two prominent electronic music producers and DJs: Skrillex and Diplo.[9] Skrillex, born Sonny John Moore on January 15, 1988, in Los Angeles, California, is an American electronic music producer, DJ, and singer renowned for pioneering dubstep and bass music.[10] His contributions to Jack Ü encompass high-fidelity production, vocal performances—such as on the track "Mind"—and dynamic live energy that amplifies the duo's high-octane sets.[11] Moore initially rose to prominence as the lead singer of the post-hardcore band From First to Last from 2004 to 2007, before transitioning to electronic dance music with his debut EP My Name Is Skrillex in 2010, marking the start of his influential solo career.[12] Diplo, born Thomas Wesley Pentz on November 10, 1978, in Tupelo, Mississippi, is an American electronic music producer and DJ specializing in moombahton, trap, and fusions of world music influences.[13] In Jack Ü, Pentz focuses on crafting beats, incorporating eclectic sampling, and infusing global rhythmic elements that blend with Skrillex's sound.[14] He founded the influential record label Mad Decent in 2006 to promote independent electronic and global bass music, and co-created the project Major Lazer in 2009, which further established his reputation for cross-cultural production.[13] The duo's partnership in Jack Ü builds on their prior collaborations in the electronic scene, including joint appearances and remixes in the early 2010s.[15]Formation and name origin
Jack Ü was formed in 2013 by American electronic music producers Skrillex (Sonny Moore) and Diplo (Thomas Wesley Pentz) as a collaborative side project, allowing them to explore joint productions outside their solo endeavors.[16] This built on their earlier informal collaboration, including the 2011 track "Amplifire," an unreleased song they worked on together during Skrillex's early dubstep phase.[17] The duo's motivations centered on creating high-energy electronic dance music tailored for festival environments, unburdened by individual label expectations or commercial pressures. Diplo initiated the idea of forming a "super duo" to focus on playful, experimental live performances that blended their distinct styles—Skrillex's intense bass-heavy production with Diplo's eclectic, genre-blending approach—aiming to deliver uplifting, crowd-energizing sets without the rigors of full-time commitments.[15] The name "Jack Ü" originates from the slang phrase "jack up," which captures the aggressive, adrenaline-pumping intensity of their music designed to "jack you up" with relentless energy and drops. The umlaut over the "U" was incorporated for visual flair, enhancing the project's bold, distinctive branding. Jack Ü was publicly announced in May 2013, with their debut performance at the Mad Decent Block Party in San Diego on September 15.[18][19][20]Musical career
Early collaborations
Skrillex and Diplo first crossed paths in the electronic music scene around 2011, when Diplo recognized Skrillex as an innovative force pushing boundaries beyond traditional hip-hop and techno influences.[21] Their initial joint effort that year was the unreleased dubstep track "Amplifier," a high-energy collaboration that sampled DJ Shadow's "Organ Donor" for its intro and showcased their shared affinity for bass-heavy, experimental sounds.[17] Released informally through Diplo's Mad Decent label channels, the track highlighted their early synergy in blending moombahton and dubstep elements, though it remained unofficial and did not see wide commercial distribution.[22] By 2012, the pair began engaging in more frequent informal studio sessions, experimenting with demos that explored fusion genres and laid the groundwork for future joint ventures, often incorporating guest vocalists and tempo shifts to test creative limits.[15] Diplo frequently invited Skrillex to participate in Mad Decent events, including early previews at label showcases, where their combined sets generated buzz among fans for the duo's dynamic stage chemistry and genre-blending transitions.[9] These appearances extended to shared festival slots, such as preliminary joint performances at events like HARD Summer precursors, building anticipation through improvised back-to-back mixes that emphasized their complementary production styles.[16] A notable example of their cross-pollination into solo work came in 2013, when Skrillex contributed production elements to Diplo's evolving projects, including features on tracks tied to Diplo's "Diplo & Friends" radio series and Mad Decent compilations, further solidifying their mutual influence amid rising individual successes.[8] These efforts culminated in a seamless transition to their formal duo formation later that year, marking the evolution from sporadic collaborations to a dedicated partnership.[17]Debut performances and breakthrough
Jack Ü made their live debut on September 15, 2013, at the Mad Decent Block Party in San Diego, California, where Skrillex and Diplo performed three original tracks for an enthusiastic crowd of electronic music fans.[23] The set included an aggressive dubstep-juke hybrid and the unreleased "Shark Patrol," a high-energy track blending Skrillex's signature roaring synths with Diplo's rhythmic flair, marking the duo's first public showcase of their collaborative sound.[24] This surprise appearance, teased earlier in the festival lineup, generated immediate buzz within the EDM community, leveraging the artists' established solo reputations to draw significant attention.[16] Building on this momentum, Jack Ü returned to the stage for a high-profile set at the Ultra Music Festival in Miami on March 30, 2014, closing the mainstage with a mix of unreleased material and remixes that captivated the large festival audience.[25] The performance featured intense drops and collaborative energy, earning widespread media coverage and further solidifying the project's viability as a major act in the electronic dance music scene.[23] Videos and fan footage from the event quickly circulated online, amplifying the duo's growing hype ahead of official releases. The project's breakthrough came with the release of their debut single "Take Ü There" on September 17, 2014, featuring vocals from Canadian singer Kiesza, whose soaring delivery complemented the track's bouncy, trap-infused production.[26] The song achieved commercial success, peaking at number 14 on the US Billboard Hot Dance/Electronic Songs chart and gaining traction on dance radio. Its accompanying music video, directed by Kyle dePinna, Dillon Moore, and Daniel Streit, captured the duo's live energy through trippy animations and performance footage, amassing millions of views and enhancing the single's cultural impact.[26] Capping a pivotal year, Jack Ü headlined Madison Square Garden in New York City on New Year's Eve, December 31, 2014, delivering a sold-out show with guest appearances from artists like Kiesza and Mac Miller, which underscored their rapid ascent to headliner status in the EDM world.[27] The event, co-promoted as a collaborative spectacle, drew over 20,000 attendees and featured explosive sets that blended their new material with crowd-pleasing anthems, cementing Jack Ü's breakthrough as a powerhouse duo.[28]Album release and touring
The duo's debut and only studio album, Skrillex and Diplo Present Jack Ü, was released on February 27, 2015, through OWSLA and Atlantic Records. Comprising 10 tracks, it featured collaborations with vocalists including Justin Bieber on the lead single "Where Are Ü Now" and AlunaGeorge on "To Ü".[29] The album debuted at number 26 on the Billboard 200 chart, selling 14,000 copies in its first week. Promotion for the album centered on a surprise digital drop during a planned 24-hour Twitch livestream DJ set by Skrillex and Diplo, which began on February 26, 2015, and included live performances and guest appearances; the stream ended prematurely after 18 hours due to police intervention at the venue.[4] This event built on the momentum from earlier singles like "Take Ü There" featuring Kiesza, which had served as an initial teaser for the project. The album's vocal-driven tracks, such as those with Bieber and AlunaGeorge, highlighted the duo's emphasis on integrating pop elements into electronic production.[30] Jack Ü supported the album with a world tour spanning 2015 and 2016, headlining major festivals including a closing set at Ultra Music Festival in Miami on March 29, 2015, where they brought out guests like Bieber and Sean "Diddy" Combs.[31] The tour extended to events such as Coachella in April 2016, where they performed on the main stage with elaborate visuals, and European festivals like Kingsday in Amsterdam for their continental debut on April 27, 2015.[32][33] These high-profile shows attracted large crowds, contributing to the duo's peak visibility during this period.[34] The album achieved commercial success, selling over 500,000 units worldwide.[35] Critics praised its innovative production, particularly the dynamic drops and integration of prominent vocal features that blended trap, moombahton, and future bass elements into accessible EDM anthems.[36][29]Hiatus and inactivity
Following the duo's extensive touring schedule, which contributed to burnout after their final European performances, Skrillex announced on August 28, 2016, via Twitter that Jack Ü would not perform at festivals or tour "for a long, long time," attributing the decision to exhaustion and a shift toward solo endeavors; the post was deleted shortly thereafter.[37][38] In subsequent 2017 interviews, Diplo elaborated on the challenges hindering further Jack Ü activity, citing disputes with Atlantic Records—Skrillex's label at the time—which complicated collaborative releases, alongside his own aversion to major label constraints and a growing preference for pursuing individual projects.[39][40] He emphasized that there was no formal breakup, describing the pause instead as an indefinite hiatus driven by these logistical and creative tensions.[39] Since 2016, Jack Ü has released no new music or undertaken any joint performances. In 2025, they revealed a completed second album featuring Florence + the Machine and Charli XCX that may never see release.[2] During this period, Skrillex focused on his solo career, culminating in the 2023 album Quest for Fire, while Diplo expanded his Mad Decent label by signing additional artists and broadening its roster of electronic and global music acts.[41][42] Although occasional hints of potential reconciliation have surfaced in media discussions, no revival has materialized, leaving the project's future collaboration unconfirmed amid reports of ongoing personal and professional strains between the members.[43]Musical style and artistry
Genres and influences
Jack Ü's music represents a fusion of electronic dance music (EDM) subgenres, prominently featuring dubstep, trap, moombahton, and future bass. This blend is characterized by high-energy drops, heavy basslines, and melodic hooks that create an intense, dynamic listening experience.[44][45] Skrillex's influence draws heavily from dubstep's aggressive edge, shaped by pioneers like Noisia, Flux Pavilion, and Excision, which infuses the duo's tracks with innovative sound design and wobbling bass elements.[46][47][48] Diplo contributes global rhythmic influences from his Major Lazer project, incorporating reggaeton, dancehall, and moombahton—a hybrid of house and reggaeton he co-created—rooted in Jamaican traditions and Latin American sounds that add infectious grooves and cultural depth.[49][50][51] Shared inspirations from house music and 1990s rave culture further define their eclectic approach, emphasizing high-production values and genre-breaking experimentation that mashes up hip-hop, electronic, and pop elements.[15] Over time, Jack Ü's sound shifted from raw, bass-driven aggression toward greater pop accessibility, merging underground club energy with broader mainstream appeal to expand EDM's reach.[1][52]Production techniques
Jack Ü's production process centered on collaborative studio sessions where Skrillex and Diplo utilized Ableton Live as their primary digital audio workstation to layer synthesizers, samples, and effects, enabling rapid experimentation and refinement of tracks. This approach was demonstrated in the creation of "Where Are Ü Now," where they manipulated Justin Bieber's vocal demo through chopping, pitch-shifting, and distortion to form the song's iconic melodic hook, transforming a simple piano ballad into an electronic hit.[53] Their sessions emphasized live improvisation, with the duo trading ideas in real-time during late-night work periods, blending Skrillex's aggressive dubstep influences—such as wobble bass lines characterized by modulated low-frequency oscillators for dynamic, gritty drops—with Diplo's eclectic sampling techniques drawn from world music loops and global rhythms. For instance, tracks like "Jungle Bae" featuring Bunji Garlin incorporated Caribbean soca elements through sampled percussion and vocal snippets, showcasing Diplo's curation of diverse cultural sounds into high-energy electronic frameworks.[29] To foster transparency and fan engagement, Jack Ü extended their creative process beyond the studio by live-streaming a 24-hour DJ marathon on Twitch upon the album's release, allowing viewers to witness improvisational mixing and unreleased previews in real time.[54]Discography
Studio albums
Skrillex and Diplo Present Jack Ü is the sole studio album by the electronic music duo Jack Ü, consisting of producers Skrillex and Diplo, released on February 27, 2015, through OWSLA and Mad Decent.[55] The album comprises 10 tracks with a total runtime of 35 minutes and 25 seconds, featuring collaborations with artists such as Justin Bieber, Kiesza, Kai, Fly Boi Keno, 2 Chainz, Bunji Garlin, Snails, and AlunaGeorge.[56] It blends high-energy electronic dance music elements with emotional vocal hooks and party-oriented anthems, drawing on the duo's signature styles of trap, dubstep, and experimental production to create a frenetic, futuristic sound designed for festival environments.[36] Many tracks originated as unreleased demos previewed during live sets and radio mixes in 2014, including a BBC Radio 1Xtra takeover where the duo showcased early versions before the surprise album drop.[57] Standout tracks highlight the album's genre fusion and collaborative approach. "Where Are Ü Now," featuring Justin Bieber, exemplifies future bass with its plucky basslines, chopped vocal samples, and emotive lyrics about longing, marking a pivotal moment in blending pop accessibility with EDM innovation.[58] Similarly, "Take Ü There," with Kiesza on vocals, incorporates moombahton influences through its rhythmic, bass-heavy groove and uplifting synths, evoking Diplo's global dance roots while delivering a high-energy club vibe.[59] Other notable cuts like "Jungle Bae" with Bunji Garlin infuse Caribbean soca elements into trap beats, emphasizing the album's diverse, adrenaline-fueled party ethos.[60] Commercially, the album debuted at number one on the Billboard Top Dance/Electronic Albums chart, selling 14,000 copies in its first week and later achieving gold certification from the RIAA for over 500,000 units in the United States.[61] It also peaked at number 26 on the Billboard 200, driven by streaming and digital sales.[57] Critically, the record received praise for its bold collaborations and sonic experimentation but faced criticism for its brevity and lack of depth beyond festival appeal; Pitchfork awarded it a 6.8 out of 10, calling it "massive-sounding" yet "stuffed to the brim," while Rolling Stone gave it 3.5 stars, lauding its "relentlessly fun" energy.[29][36]Singles
