Kanye mad at Lollapalooza

Kanye West was midway through his set at the festival in his own hometown of Chicago when the sound was suddenly cut off.

New York Daily News reports: "He threw a hissy fit. When the sound didn't work, he started yelling that he came all the way out to Chicago and he couldn't believe he was being treated like this."

West was still mad about it later that evening, and refused to attend a party he had throw for the production trio SA-RA.
