SOUNDGARDEN singer Chris Cornell reportedly called Kanye West "retarded" as the Big Day Out's headlining acts faced off against each other at the Gold Coast Big Day Out.
Reports have emerged of a growing spat between the two acts after West's soundcheck on a neighbouring stage drowned out part of Soundgarden's set during the Sunday leg of the touring Australasian festival.
Soundgarden's fans booed when West's sound check interfered with their performance.
Cornell reportedly told the crowd: "Sounds like there's children playing music there, retarded children, retarded as in held back ... There's no other word for it."
That wasn't the only problem on the night. Big Day Out organisers were quick to point out that a 45-minute delay in the start of West's performance was caused by equipment damage following a sudden storm.
