Frank The Butcher enlists two of hip-hop’s greatest lyricists—Killer Mike and El-P—for his next episode of The Butcher’s Block. Both their albums (R.A.P. Music and Cancer 4 Cure), are on display in this clip, during which they talk about a key track from each one.

Watch Frank purchase the albums, give them a quick listen, and ask about the back stories behind El-P’s “For My Upstairs Neighbor” and Killer Mike’s “Reagan.” These interviews all went down during a stop on “The Into The Wild Tour” where they recently hit New York for a solid performance.
