As we reported yesterday, Kanye West served as a headliner at the Big Day Out 2012 Music Festival in Gold Coast, Australia. But what we didn't know is that he managed to piss off one of his fellow performers. Apparently seminal Seattle rockers Soundgarden were on an adjacent stage and they weren't too happy with the sounds of Yeezy's set. As PopDust reports, frontman Chris Cornell said to the crowd: "Sounds like there’s children playing music there. Retarded children, retarded as in held back. There’s no other word for it."

Oof. Anyone else think Cornell went way too far?
