Before El-P releases his next solo opus, Cancer For Cure, on May 22, he's dropping a collaborative album with Killer Mike the week prior. It's called R.A.P. Music and it features the larger-than-life Atlanta rapper spitting exclusively over beats from El-P, who also spits a guest verse. Other features include T.I., Trouble, Bun B, Scar, and Emily Panic on this massive, Bomb Squad-indebted album. You can stream R.A.P. Music in its entirety by clicking the Spin link below. It drops May 15.
