Jack Ü

Jack Ü is an American EDM DJ duo, side group and collaborative project consisting of electronic music producers Skrillex  and Diplo formed in 2013. They released their first official single, "Take Ü There", featuring vocals from  Kiesza, on September 17, 2014. On February 3, 2015, the duo announced that they would be working with Missy Elliott on a remix to "Take Ü There". They released their debut album, Skrillex and Diplo Present Jack Ü, on 27 February 2015.

Jack Ü performed at Ultra Music Festival Miami in 2014. They also performed at Ultra Music Festival in 2015 with the entire "Jack Ü crew", featuring live contributions from CL, Kai, Diddy, Kiesza and Justin Bieber.

According to Skrillex, the collaboration is called 'Jack Ü' because it refers to how the music 'jacks you up' with its high energy beats and bassline.

History
On September 15, 2013, Jack Ü's debut performance took place at Mad Decent Block Party in San Diego with 3 original tracks: a dubstep-juke hybrid track known as "Shark Patrol", "Bounce it", and a very early version of their collaboration with AlunaGeorge that would later be released as "To Ü"

Diplo announced the project by releasing the Mad Decent Block Party lineup with Jack Ü playing at multiple stops on the tour. After some guessing by many of who Jack Ü was, Diplo finally came out to reveal that "Jack Ü ... means Skrillex and Diplo together".

The two have worked with each other on assorted projects over the past five years starting with Skrillex singing and playing guitar on a record for Major Lazor, one of Diplo's other projects. In 2011, Diplo also worked on a song with Skrillex titled "Amplifire" (though it was never completed or released) for Bangarang.

On March 30, 2014 Jack Ü was given an hour-long slot to play at the Ultra Music Festival. The set included a wide variety of genres featuring songs from Skrillex's then newly released first studio album, Recess, and including some old school hip hop with DJ Kool's "Let me clear by throat". They later played the 2015 Ultra Music Festival.

They collaborated on a song that combines trap and dubstep elements and features vocals from Korean pop artists CL and G Dragon titled "Dirty Vibe" for Skrillex's album Recess. When asked about how the two ended up forming Jack Ü, Diplo stated that Skrillex "was one of the first producers I met when I moved to LA...we just [have] always been really close musically with our ideas." The two get together in downtown LA or in hotel rooms when on tour to make their songs.

On December 31, 2014 Jack Ü headlined a concert at Madison Square Garden. Besides their (Diplo and Skrillex) performance, other performers included A$AP Ferg, Diplo, Skrillex, Rudimental and Yellow Claw. The concert was broadcast live on Yahoo.

On February 27, 2015, the group released their debut album. They commemorated the event by streaming a 24-hour live DJ set on Twitch, which was shut down 18 hours into the set.

Jack Ü had over 9.6 million Shazams in 2015.

Jack Ü performed at a 2015 Clippers half-time show along with Kai, Fly Boi Keno and several other celebrities and dancers, later releasing an official video in December.

On 28 August 2016, Skrillex wrote on his Twitter page that Jack Ü is done touring "for a long long time", a tweet that was shortly deleted. In March 2017, Diplo described in an interview the difficulty of working with Skrillex while Skrillex is signed to a "major label", Atlantic Records.

Controversy
On September 1, 2014, Seth Troxler, was set to play his set at the Robot Heart stage at the Burning Man Festival. However, due to some of his entourage not being allowed to join him behind the DJ decks, Troxler refused to play. Those in charge of the Robot Heart stage needed someone to fill in for Troxler and they asked Skrillex to help. Skrillex played for about half an hour before inviting Diplo to come onto the stage for them to perform as Jack Ü for the rest of the set.

Some of the Robot Heart crowd were unhappy, because Skrillex and Diplo are mainstream producers, and the Robot Heart stage is more about underground artists and songs. To finish up their set Diplo mixed the song "Africa" by Toto into DJ Snake and Lil Jon's platinum record "Turn Down For What?" as "an inside joke".

Rumors later surfaced that the two were booed off the stage and forced to end their set early due to playing "Turn Down for What" at a stage that was meant for underground music. Diplo linked to a long statement on his Twitter, saying that "there was no booing... no bad vibes... Everything we did there was good fun and all the people that attended know it".
