Flosstradamus has built one of music’s most devoted underground cult followings through pioneering what’s become the biggest sound in the rave world right now–an extremely synergistic combination of arena-sized EDM and street-level Southern hip-hop known as “trap.” For their latest track, a collaboration with British producer TroyBoi, they give their formula an intriguing tweak. “Soundclash” still has the vertigiously deep bass, head-bangable drops, and insistent melodies that the Floss brand is synonymous with, but the three producers work in touches of reggae and a little Aphex Twin-style glitchiness that takes the track in a new direction, albeit one that’s still singlemindedly focused on turning all the way up.
