NEW YORK — Metallica and Pearl Jam will headline the 2008 Bonnaroo Arts and Music Festival, concert organizers announced.

The seventh annual festival will be held June 13-15 on a 700-acre farm in Manchester, Tenn. Notably absent from the announced slate was Led Zeppelin, who has for months been rumored to be heading to the festival.

The British band reunited in December for a single show and speculation has abounded that a world tour is possible. Last week, guitarist Jimmy Page said he wanted to tour with singer Robert Plant, bassist John Paul Jones and drummer Jason Bonham, who replaced his father, John, who died in 1980.

Instead, Plant will be heading to Bonnaroo with bluegrass star Alison Krauss, with whom he made the hit duet album, "Raising Sand." The festival organizers, alluding to the Led Zeppelin reports, trumpeted a performance by the cover band Lez Zeppelin at the festival.

Also scheduled to perform are Kanye West, Jack Johnson, My Morning Jacket, Willie Nelson, B.B. King, Phil Lesh and Friends, Sigur Ros, the Raconteurs, Against Me! and Death Cab for Cutie.

A lineup of comedians performing in the festival's "Comedy Tent" will include Zach Galifianakis, David Cross, Janeane Garofalo, Jim Norton, Mike Birbiglia and Brian Posehn.

Tickets to the seventh annual festival are on sale now. More acts will be announced later, with an expected total of over 100 bands.
