Speaking after Metallica topped the bill on the Pyramid Stage in June, the drummer reveals his tip for 2015 in our new issue, Q338 out tomorrow (29 July).
“Can I throw my first bid for who I think Michael Eavis has booked for next year?” he asks.
“I have heard it might be a band whose lead singer is British, but none of the rest of the band are. Yeah… AC/DC! Come on! Can you imagine that?”
Ulrich also tipped several fellow rockers who could follow his lead and headline at Worthy Farm, telling Q's Mark Blake that both Foo Fighters and Black Sabbath would "blow that shit up!"
