Big Sean's Finally Famous tour hit the Best Buy Theater in New York City last night and it's not a grand event in the Big Apple without some surprises. During his performance of "Marvin Gaye and Chardonnay," B.I.G. Sean Don brought out Kanye West to rock out to the single for the crowd.
He also debuted a new track titled "All I Know" from his upcoming sophomore album, currently still in the works. Check out his performance of that and "Keep It G" below.
