Slipknot frontman Corey Taylor launched into a foul-mouthed rant about Coldplay frontman Chris Martin and the band's latest LP during a TV interview.
The British rockers' Viva la Vida received critical acclaim when it was released earlier this year.
But Taylor is not a fan of the record, or singer Martin - and made his thoughts known in a profanity-packed U.K. TV interview.
He tells Zane Lowe's MTV show, "That is one of the most self-celebratory pieces of shit I've ever fucking heard in my entire fucking life.
"Go suck a fucking dick. Are you watching Martin? Suck it. Go eat a bag of shit.
"I fucking hate that album. It's music to wipe your ass to."
