“Our fantastic line-up will be sure to excite festival-goers of all ages,” said Branson, whose entrepreneurial focus in on the environment. “We’re going to redefine cool at one of the hottest and greenest destinations for live music this summer.”

Local indie promoter Seth Hurwitz of I.M.P. said, “With two stages and a dance tent, we’re very selective about our line-up. It’s all about quality over quantity, the flow of the event and how the bands overlap. With the limited slots available, we have to keep it A-list talent from top to bottom.”
