American electronic duo Jack Ü is the side project of EDM giants Diplo and Skrillex, with the pair combining to create a mixture of house, dubstep, and trap. After collaborating on numerous projects, including Skrillex's appearance on Diplo's Major Lazer project and Diplo's credits on Skrillex's Bangarang EP and full-length Recess, the pair made their first appearance together at the Mad Decent Block Party in 2013. They went on to play a host of festivals together, mixing varied sets of music, and eventually recorded some original material. The resulting single, "Take Ü There" with Kiesza on vocals, was released in 2014. Their debut full-length arrived a year later. Skrillex and Diplo Present Jack Ü (OWSLA/Mad Decent) spawned the multi-platinum hit single "Where Are U Now" with Justin Bieber and topped the dance/electronic charts in Australia and the U.S. upon release. ~ Scott Kerr & Neil Z.
