Hip-hop artist and producer extrordinaire is back after a long-awaited hiatus with a banging record that features guest appearances from Killer Mike, Mr. Muthafuckin' eXquire. After taking some time away from the studio to deal with his now-defunct label, Def Junx, El-P has returned with some purpose and some new-found attention - aided by his recent appearance on the Late Show with David Letterman.
