Danny Brown’s one of the few rappers who can take a song called “Kush Coma” and make it a total blast, despite the goofy title. With his squawky punchlines and stoner swagger, Brown’s being compared more and more to the late Ol’ Dirty Bastard, a third of whose name was the inspiration for Brown’s forthcoming album, Old, which hits shelves this summer. Despite the undercooked, faux-reggae hook, “Kush Coma” is an impressive, genre-blending track, a collision of spooky Umberto-style synths and hollow 808s. Skywalkr, Brown’s Bruiser Brigade brother (try saying that three times fast), lends the production an impressionistic touch, giving Brown plenty of space to freak out. The album version apparently features A$AP Rocky.
