The annual festival, which was co-founded by Gov’t Mule and Allman Brothers Band guitarist Warren Haynes, has been expanded to three days this year to accommodate growing interest from artists and from fans.

The roster for the June 1-3 event is a who’s-who of jam-band faves including Gov’t Mule, G. Love & Special Sauce, Umphrey’s McGee, Michael Franti & Spearhead, Robert Randolph and The Family Band, New Orleans Social Club, Ozomatli, Tea Leaf Green, RAQ and many others.Tea Leaf Green and RAQ will also be doing special late night performances.

Mountain Jam also joins the growing list of festivals that have gone green. Community Energy will donate New York wind energy credits to the festival to offset 100% of the electricity used at this year’s event. Vendors at the event have been asked to recycle everything from cardboard to aluminum and plastics.

Styrofoam products will not be permitted. Some vendors will also use solar power as their main energy source.

In addition to the eco-friendly measures taken by festival organizers, volunteers from Rock the Earth will be on hand to educate festival-goers about important environmental issues. Festival amenities are family friendly, and include on-site camping, a 24-hour full service lodge, a children’s area with arts & crafts and singing and dancing with Uncle Rock, a children’s musical entertainer.
