Riff Raff, who claims he’s the number one sleep walking booty grabber in Sweden, dropped a new mixtape called Summer Of Surf. This serves as more as a round-up of his latest songs with tracks by Kitty Pryde ("Orion's Belt"), Chief Keef ("Cuz My Gear"), Lil Debbie, and more. He just made an appearance on Meyhem Lauren’s Respect The Fly Shit, and should be working with in-demand producer Harry Fraud on a new mixtape. Riff is certainly keeping busy this summer.
