EL-P

Having El-P and Killer Mike on the same lineup seems too good to be true. Each released one of the best and most fascinating hip-hop albums of the year, but they otherwise come from two different rapper worlds. El-P (Jaime Meline), the Brooklyn-reared indie-rap guru and Def Jux label proprietor, actually produced the Dirty South protégé’s truly killer new one, “R.A.P. Music,” which has the playful Southern-boogie flavor of his pals OutKast but also boasts a classic Reagan-era, rap-vs.-the-world gangsta edge. El-P’s own new one, “Cancer 4 Cure” — only his third solo album in over a decade — has an edge unlike no other, with dark, paranoid overtones meshed over some of the boomingest beats of memory. Newly signed to Universal, Mr. [M.F.] eXquire opens along with Despot. It should be one crazy show. Chris Riemenschneider
