Reverb, a non profit founded by the musician Adam Garner and his wife Lauren Sullivan, has the mission to make festivals and touring as environmentally friendly as possible. They provide the money, commitment and manpower that the bands or organisers couldn't. They recycle, compost, buy local food, advise on how to avoid waste, make sure sustainable products are used down to the soap, carbon offset, use biofuel, provide solar power charge stations for phones, educate fans, encourage people to car pool or recycle, collect contacts and money from fans for different charities – and all of it in collaboration with bands. Some of the bigger ones they work with are the Dave Matthews Band, Maroon 5 and Jack Johnson.
