I worked for several months as the film director for Finger Lakes Unplugged, a social networking site. We went to music festivals, set up a tent in the performers area, bought some refreshments, set up cameras, furniture, microphones and lights, and just shot what happened next. We called it "The Green Room Lounge." And because every band had a different configuration, and the light coming in from outside was always changing, we got really good at scrambling for shots.
