El-P's self-described "fight record" Cancer4Cure arrives May 22 through Fat Possum. You've already heard "The Full Retard", now here's a new one called "Tougher Colder Killer", which features Killer Mike and Despot. (El-P and Killer Mike also have an album together, R.A.P. Music, coming out in May). El-P, Killer Mike, and Despot will tour together this summer, along with Mr. Muthafuckin' eXquire. Full schedule here.
