Paving Justin Bieber's way to respectability with "Where Are Ü Now" was just the start for Diplo and Skrillex, a.k.a. Jack Ü. They kept busy in 2015, and if you want to know just how busy, watch the video for "Mind," released in February, which is packed with clips of their globetrotting performances. Diplo's EDM global fusion smorgasbord Major Lazer will also be performing at the festival, fresh from the trio's historic March gig in Cuba. While in Cuba, Diplo also promised that new Jack Ü material would surface around Coachella time.
