Chance The Rapper has been hosting OpenMike nights for Chicago-area high schoolers for the past couple months as a way of getting them off the streets and into music and poetry.

The students got a quite a treat yesterday when Kanye West showed up as a surprise guest at the University of Chicago auditorium.

It started when Kanye's guy Vic Mensa came out and did his track 'U Mad.' When it was time for Kanye's verse 'Ye jumped on the stage and the audience went completely bonkers.

Mensa and West went on to do 'All Day' and then Chance joined them for 'We Don't Care'. Check out some fan footage:
