Few artists in underground hip-hop—few artists in any type of hip-hop—have the range of this Colorado MC, the rare sort of rare lyricist who can spit quick, devastating rhymes filled with vivid depictions of carnage then drop back and speak from the heart, opening his life up to all his fans. On The Return of the Prodigal Son, his new LP, he even sings, bending notes while experimenting with AutoTune. He also produces all his own beats.
