The 600 sweaty Brooklyn bowlers at Pitchfork's #Offline Festival were in for a treat 2am Saturday night.

Kanye West came out to celebrate the third anniversary of collaborator and friend DJ A-Trak's Fool's Gold imprint and rocked the audience with five of his newest Internet hits: "So Appalled", "Monster", "Devil in a New Dress", "Power", and "Runaway".

The night did not end there, with Wu-Tang founding member GZA following up Kanye's set with a sing-along to "Shimmy Shimmy Ya" and "Liquid Swords."
