With the second part of Bang 3 expected to release tonight, we have received one of the most anticipated tracks off of the project. On this one, Sosa connects with Lil' B for 'Irri.' The two have shown admiration for each other for years, and today we get to hear their first official collaboration. The track can be streamed below, and Chief Keef's Bang 3 Pt. 2 can be pre-order on iTunes.
