2012 EP, a collaboration between Travis Barker and Yelawolf. The EP, which is produced entirely by Barker, features guest vocals from Tim Armstrong (Rancid, Operation Ivy, Transplants), and Skinhead Rob (Transplants), as well as scratches and cuts by Mixmaster Mike (Beastie Boys). The EP is an eclectic mix of musical genres both guys enjoy--including rap, punk, ska and more. The renowned drummer most known for his involvement with Blink 182 and the Shady Records protege have collaborated before but this is their foray into a project of this kind.
