The hard, blippy, propulsive sound of L.A. producer DJ Mustard has been the dominant sound of West Coast rap for the past few years. And while Mustard released a proper album called 10 Summers last year, his new mixtape, the confusingly titled 10 Summers: The Mixtape, Vol. 1 is the first of those that he’s released since 2013’s excellent Ketchup. The new tape has appearances from people like Ty Dolla $ign, the Game, Iamsu!, and Dom Kennedy, but it’s more dominated by relative unknowns like DrakeO, Skeme, RJ, and Choice. Check it out below.
