Migos released their major label debut Yung Rich Nation at the end of July, and a month ago, they put out the Back To The Bando mixtape. Because they’re insanely prolific, they’ve just dropped another mixtape, the fourth installment of their Streets On Lock series with Rich The Kid. Streets On Lock 4 features Rae Sremmurd, iLoveMakonnen, 2 Chainz, Jeezy, Waka Flocka Flame, and a bunch of other people, and you can listen to it below via Pitchfork or download it here.

Migos are also teaming up with the equally insanely prolific Young Thug on the Migos Thuggin tape, which will be out on Halloween.
