Radiohead guitarist Johnny Greenwood has said that the band are not sure how relevant the Grammy Awards are.
The band scooped two awards for their latest album IN RAINBOWS, which was first released as a digital download in 2007.
However, speaking ahead of the ceremony, Greenwood said he was unsure about the importance of the awards.
"I'm confused, because whenever I watch The Simpsons they're very rude about the Grammys. It's hard to know how important they are," he said.
The band were joined by the University of Southern Carolina's marching band for a version of their song 15 Step.
Greenwood recently won a Kermode Award for his work on the soundtrack of Oscar-winning movie THERE WILL BE BLOOD.
The big winner at the Grammys was Robert Plant who picked up five awards for RAISING SAND, his collaboration with Alison Krauss
