It was between bites of the excellent crudité backstage at last May's Mobb Deep show that we learned from Alchemist that he'd be putting in work on Roc Marciano's forthcoming Reloaded . Not that this should be a surprise to anyone given their musical compatibility. But little did we realize that their collab would also result in an entire Marcberg/Gangrene (a/k/a Alchemist + Oh No) EP - dubbed Greneberg - dropping this summer . The first blast, "Jet Luggage," is as raw as anyone could hope, with Roc letting off his trademark crime-rhyme couplets ("Dress spiffy/Finesse the Mac-11 out the Dickie"), an aggro Al promising to "piss on peasants," and Oh No adopting a surprising flow that's less Oxnard than Ox- hard . Please listen to their "Luggage" below. Greneberg arrives July 19th on Decon.
