A three-day music festival in Great Barrington, Massachusetts, nestled within the Berkshire Mountains at the Butternut Basin Ski Area. Held annually in August. Presented by Gamelan Productions and High Sierra Music Festivals. Attended by hippies, with a great many jam bands playing non-stop. Camping for all, food, beer, and stuff to buy.
Considered one of the summer highlights for music festival attendees on the east coast.
