Queens Of The Stone Age frontman Josh Homme has slammed Jay-Z, calling him a “kook.”

Homme made the comments during a candid interview on “The Strombo Show” on Canada’s CBC Radio 2, where he was talking about his experiences at Jay-Z’s ‘Made In America’ Festival.

Homme believed his band was out of place at the festival, and called out Jay-Z’s extreme security measures and his treatment of the band.”That guy’s a kook, you know.” Homme said.

“He has his security frisking the bands on the way in. I just told them if you open up my bag I’m not playing so I guess it’s up to you whether we are playing or not

“The idea they frisked all my guys, means you’re in some different place… No-one has ever done that,” he continued.

Homme also criticized the highly commercial nature of the festival, which has a full title of “The Budweiser Made In America Festival.” Not only did Homme feel out of place in a line up that seemed picked straight out of the most commercially successful acts of the moment (Beyonce, 2 Chainz, Imagine Dragons), he felt the rapper was being insincere: “He also gave us some champagne and wanted us to take a photo with it, and I thought that’s not a gift that’s a marketing tool. So I destroyed it. Because I thought it was rude overall,” he explained.

> I imagine Homme destroying the champagne went something like this.
