Yesterday saw two leaks off Rick Ross‘ new album God Forgives, I Don’t: “Diced Pineapples” with Wale and Drake, and “Sixteen,” an eight-minute track featuring Andre 3000. Today brings the enormous, siren-blaring “911,” which is set to show up on the album’s second half. It is–at least by comparison to, say, Ross’ collab with Usher–probably the heaviest thing we’ve heard from the record, which is out July 31 via Def Jam. Stream it below.
