Compton’s own Villain in Black, MC Ren, is back with a new album on deck and a freshly activated SoundCloud account chock-full of goodies. Last we checked, the former N.W.A. member is in his mid-40s and living in Palm Springs — according to Jeff Weiss’ for LA Weekly — but he sounds mightily menacing over a surging, trap-addled E-A-Ski beat on “Rebel Music.” That’s the titular track from a forthcoming album of the same name. Stream it below, and beneath that, three older tracks: “Nigga Called Ren,” “Same Old Shit,” and the classic “Final Frontier.” (Beware strong language regarding beat-downs, “bitches,” slugs, and Sega gaming consoles.) “Rebel Music” throws back to a few gangsta themes but swaggers like a Dead Prez anthem — smart, confident, and hard.
