24. Killer Mike "JoJo's Chillin'" (2012)
Album: R.A.P. Music
Label: Williams Street
Dungeon Family alumnus Killer Mike and New York underground rap czar El-P met randomly through a mutual acquaintance in 2011, who suggested they work together. The collaboration quickly became R.A.P. Music, a whole album with El on beats and Mike on rhymes. El's clattering, futuristic boom bap and Mike's country drawl seemed like a weird mix on paper, but tracks like the bad-guy-wins story song "Jojo's Chillin" revealed a union as creative as it was improbable.
