Big Sean was on stage at 'The Belmont' with 'Trae Tha Truth' when he got a surprise from his G.O.O.D. music mentor, Kanye West.

It looks like the days of 'SXSW' being a showcase for undiscovered artists are on hold for a while.

Heavy hitters like Kanye, Jay-Z, Lil Wayne and many more have been popping up on stages all over the music festival.
