UPDATE: Here’s the full set.

Over the weekend, Chicago rap icon Common headlined AAHH! Fest, a rap festival in his hometown. Or anyway, Common was billed as the headliner. Things didn’t really work out that way. The festival, which Common curated, also featured appearances from Dave Chappelle, Jay Electronica, Lupe Fiasco, and De La Soul. And Kanye West, who apparently everyone knew would be a surprise guest, came through to do a full 16-song greatest-hits performance. Consequence Of Sound reports that Kanye brought Common, Jay Elec, and Vince Staples to the stage when he performed “Clique,” but no video of that performance has yet made it to the internet, and I haven’t been able to figure out whether those guys actually rapped on “Clique” or what. Also of note: Someone crowdsurfed in a wheelchair while Kanye was on; that’s what’s happening in that video. Below, you can check out fan-made video of Kanye and Common doing the College Dropout oldie “Get ‘Em High” together. (Warning, though: You can’t hear much of anything.)

Also, Kanye is still fulfilling his community service by teaching at an L.A. fashion school. Here’s a photo, via Hypetrak:
