The team-up came toward the end of Big Sean's show at the Best Buy Theatre, where the rapper topped a bill that also included CyHi the Prince and Shawn Chrystopher, his cohorts on the I Am Finally Famous' tour. The 30-city trek takes its name from Sean's debut album, 'Finally Famous,' which arrived earlier this year.
The website RealTalkNY had their cameras rolling when Kanye dropped by, and in the video (below), a shirtless Sean can be seen rocking a black robe, looking like a cross between Hugh Hefner and an energetic prizefighter. Yeezy opts for a gold chain, red plaid shirt and what appear to be leather pants.
After the duo finish their song, Sean big-ups the other artists signed to West's G.O.O.D. Music label and walks offstage with his arm around his boss. The collaboration capped a night in which the Detroit MC debuted two new tunes, 'All I Know' and 'Keep It G,' both of which he may be considering for the sophomore album he's already working on and hopes to release next year.
