Mirror, mirror on the wall, who’s the greenest music festival of them all? This year I’m placing my bets on Rothbury. Now in its second year, the music festival – which just wrapped up its four-day stint yesterday in Rothbury, Michigan – calls itself a “party with a purpose.”

True to its tagline, Rothbury does all the important green event stuff like reducing waste, recycling, composting, using clean energy, promoting carpooling, and more. But what sets this music festival apart from its peers is the Think Tank, an event within the event that offers concert attendees the opportunity to discuss pressing environmental problems and potential solutions with scientists, scholars, writers, politicians, corporate leaders, activists, and artists. This year’s theme? Joining the new green economy.

It’s not all talk either. In addition to panel discussions, Rothbury features how-to workshops that covers topics like finding a green job, making your home and office energy efficient, growing your own organic food, and becoming an eco-fashionista.

For those of you interested in the  music – and why wouldn’t you be with superstars like the Dead, Bob Dylan, and Willie Nelson topping the bill- you can view photos and watch videos of the festival’s highlights here.
