From Idolator: Led Zeppelin is playing the Bonnaroo festival this summer. Or so we hear. The band "confirmed" the date in an email to Bob Lefsetz of the classic rock-worshipping The Lefsetz Letter: "Zeppelin just confirmed for Bonnaroo. They can't officially announce until after the London gig so pass it on! Also Metallica is confirmed on the bill too!" sayeth Bob. So, as long as you don't mind sloppin' it in the mud at the nation's top head-shop convention, get ready for some juice to run down your leg, Bron-Y-Aur stompers!
