Career Highlights: His debut album Monster peaked at No. 10 on the Billboard charts and No. 4 on the Top R&B/Hip-Hop chart. He has mad guest appearances on tracks, including Bone Crusher's "Never Scared," which peaked at No. 26 on Billboard. He signed to Grand Hustle in 2007.

The "Killer" in Killer Mike ain't just a name. Every time he steps onto the mic, he's ready to assault with a dizzying amount wordplay and unrelenting lyrics (peep "Snappin' and Trappin'" from Stankonia). He's recently peaked with R.A.P Music, a Southern tour de force that's both aggressive and self-aware.
