Even in a crowded field of hip-hop megastars, there’s no denying Danny Brown is a straight-up original. Recording since his teens, the dynamic young rapper burst out of Detroit’s underground hip-hop scene — first with his self-released 2010 record The Hybrid, and again with the highly-praised XXX in 2011, an album that pushed Brown to hip-hop’s top shelf thanks to his skillfully concise lyrical voice, a hypnotic flow, and sharp humor.
