Before Brockhampton even played a note on Saturday evening, the Mojave tent was jammed full of fans chanting their name. Despite delays and microphone issues (which main member Kevin Abstract later profusely apologized for), the L.A. hip-hop collective still pulled off one of the weekend's most exciting sets. Donning bulletproof vests, backed by a string section and rolling with their special guest DJ A-Trak, Brockhampton delivered the finest cuts from their trilogy of Saturation albums, with a smattering of boy-band choreography to boot. The performance mixed the energy of early Beastie Boys, the dynamic interplay of peak Wu-Tang Clan and the creative mischievousness of Odd Future. The energy around Brockhampton and their fiercely loyal followers already feels less like breakout-band buzz, and more like a developing cultural movement.
