Air out the tent and break out the Jerry Bears. The music festival that put Rothbury, Mich., on the map in 2008 is ready for round two with the only scheduled 2009 performance by The Dead (as in “Grateful Dead” minus the deceased Jerry Garcia). On Monday, Rothbury Festival organizers announced a starstudded lineup of iconic headliners, which in addition to The Dead, includes Bob Dylan, The Black Crowes, Damien Marley and Nas, Willie Nelson, Girl Talk, The Disco Biscuits, Cold War Kids, Matisyahu and more.

Tickets for the festival, which takes place July 2 through 5 at the Double JJ Ranch, go on sale at noon on Friday, March 20. Weekend passes are $249.50 plus service charge, with RV passes going for an additional $125.

But you dont have to empty your pockets to be a part of the fest. Volunteers for the eco-minded festivals Green Team can score passes in exchange for a commitment to help keep the grounds clean and enforce recycling.

Created with the purpose of offering a sustainable music event, Rothbury organizers pride themselves on their commitments to keeping it “green” and creating a near-zero waste festival by using recycled and organic materials to print tickets, T-shirts and other merchandise and by offering recycling services on site. A percentage of the festivals profits are also donated to environmental causes.

From reggae pioneers Toots & The Maytalls to bluegrass greats Ralph Stanley and the Clinch Mountain Boys, the festival offers a wide range of sounds. For the indie-rock set, there’s Pitchfork favorites Man Man, Broken Social Scene and the Hold Steady.

Michigan acts getting a nod include Lansing’s Steppin’ In It and Detroit-byway-of-East Lansing rockers The Hard Lessons.
