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

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.
