The fourth annual Caravan Music Festival will once again bring a boatload of Philadelphia bands to the woods of Maine of a three day concert of music, fun, lake swimming, exhaustion, and who knows whatall else. The massive lineup of the festival – which happens August 2nd, 3rd and 4th – includes a lot of returning favorites like Cheers Elephant, hosts / organizers Penrose, The Lawsuits, Juston Stens and the Get Real Gang and more. There are also some newer-ish names like Pine Barons, and perplexing others such as The Jawn and Vitamin Cheese. As a general rule I’m skeptical of the word “cheese” getting used in band names, but I’ll give these guys the benefit of the doubt. Lineup and details after the jump. Below, watch Cheers Elephant performing “Party On, Darwin” at Caravan 2011.
