Yesterday, Pusha T released his new single, “Untouchable,” the Biggie Smalls-sampling, Timbaland-produced head banger of a lead record, in preparation for his impending new album, King Push. A couple years ago, he headlined the Brooklyn Hip-Hop Festival, and performed some of his deepest, best cuts live, including his sparring match with Kanye West, “New God Flow,” off the G.O.O.D. Music compilation album, Cruel Summer.
