Every year, the people behind Record Store Day pick one famous artist to help them advance the cause of getting people into brick-and-mortar stores to drop a bunch of money on limited releases once a year. Last year, it was St. Vincent. And this year, the duo of Killer Mike and El-P are doing the honors. It’s not a bad fit; once upon a time, as the visionary behind Definitive Jux Records, El-P did more than anyone else to make underground rap CDs into collectible mini-art objects. Here’s El’s announcement:
