Iron Maiden vocalist Bruce Dickinson recently gave the punk genre a decent bashing, calling the music rubbish, and branding musicians as wannabe metallers.
Chatting with the Guardian, Bruce was asked about the way metal is judged as "a lesser art form."
"The closest the 'art establishment' ever came to embracing metal was punk," the singer replied. "The reason they embraced punk was because it was rubbish and the reason they embraced rubbish was because they could control it.
"They could say: 'Oh yeah, we're punk so we can sneer at everybody. We can't play our f--king instruments, but that means we can make out that this whole thing is some enormous performance art.'
"Half the kids that were in punk bands were laughing at the art establishment, going: 'What a f--king bunch of tosspots. Thanks very much, give us the money and we'll f--k off and stick it up our nose and shag birds.' But what they'd really love to be doing is being in a heavy metal band surrounded by porn stars," Dickinson added.
During the rest of the chat with fellow musician Frank Turner, Bruce dubbed fame an "excrement of creativity," going on a second ripping spree, this time focusing on Glastonbury performers.
"I see these wankers onstage at places like f--king Glastonbury wandering around as if they had a mirror attached to themselves, gurning for the f--king cameras and paying no attention whatsoever to that kid in the front row.
"That's what makes the difference between Maiden and everything else. I'm not interested in being famous," the singer noted. "Fame is the excrement of creativity, it's the sh-t that comes out the back end, it's a by-product of it. People think it's the excrement that you should be eating. It's not. It's the creativity and the audience and being there in the moment."
