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.
