Billy Corgan has lashed out at Radiohead.

The Smashing Pumpkins frontman has blasted the Oxford band as "pompous" and says he is horrified that some people think Radiohead's Jonny Greenwood is more valuable than Deep Purple's Ritchie Blackmore.

"I can't think of any people outside of Weird Al Yankovic who have both embraced and p****d on rock more than I have. Obviously there's a level of reverence, but there's also a level of intelligence to even know what to p**s on. Because I'm not p***ing on Rainbow. I'm not p***ing on Deep Purple. But I'll p**s on f*****g Radiohead, because of all this pomposity. This value system that says Jonny Greenwood is more valuable than Ritchie Blackmore. Not in the world I grew up in."

However, Billy also admitted Blackmore is a better guitarist than he is: "So I find myself defending things. Is Ritchie Blackmore a better guitar player than me and Jonny Greenwood? Yes. Have we all made contributions? Yes. I'm not attacking that. I'm attacking the pomposity that says this is more valuable than that. I'm sick of that. I'm so f***ing sick of it, and nobody seems to tire of it."
