Big Sean sparked a party last night on Jimmy Kimmel Live, performing a pair of songs on the outdoor stage while beach balls bobbed through the crowd. Wearing an Ol' Dirty Bastard T-shirt, the rapper started with "Beware," his easy flow unspooling over a smooth beat until he paused for Jhene Aiko to sing the hook.

His second song, "Fire," featured a deeper rhythm thanks to a quartet of percussionists backing him as he let fly with speedy rhymes over a sampled chorus of voices chanting the title of the song.

Both tunes are from Big Sean's upcoming album Hall of Fame, which is due on August 27th.
