Danny Brown has made his living being a rapper on the fringe of things– eclectic, frequently filthy and absurd while having incredible charisma; he gets away with more risks than most artists make in their lifetime. On Atrocity Exhibition, named after the opening Joy Division track from Closer, Brown fully embraces his id and pushes aside any and all consequence. Like “When It Rain,” there’s little on Atrocity Exhibition that you have ever heard before, much less on anything that attempts to pass as mainstream music. It’s dark, the instrumentals and samples are about as left-field as it gets, and sometimes there isn’t even a discernable beat. It’s the hip-hop version of free jazz– deconstructed and disjointed while still somehow making sense.
