Mixing Twista's speed, De La Soul's D.A.I.S.Y. Age attitude, and the modern swagger of the Tech N9ne-driven underground, rapper R.A. the Rugged Man is a favorite guest star for the likes of Mobb Deep, Wu-Tang, and Notorious B.I.G., but his own discography is surprisingly slim. In the early '90s, deals with Jive and Priority fell through. He went indie and released Die, Rugged Man, Die on Nature Sounds in 2004. Legendary Classics, Vol. 1, compiled in 2009, rounded up his collaborative releases. Talib Kweli, Tech N9ne, Krizz Kaliko, and Masta Ace were some of the names that joined R.A. on his 2013 release, Legends Never Die. ~ David Jeffries
