The Roots Play for Planet

Third Eye Blind, Michelle Shocked also team up for S.F. enviro-fest

Last year's festival in Golden Gate Park featured Bonnie Raitt, Alanis Morissette, Cake and De La Soul, and created a template for environmentally conscious, large-scale events: We the Planet inspired both the Warped Tour and Lollapalooza to run on biodiesel fuel.

For Shocked -- also a member of the honorary advisory panel that includes Perry Farrell, Morissette, Joan Baez and actors Gillian Anderson and Woody Harrelson -- the goal of the event is simply to be "a realization of the vision of Julia Butterfly." Hill is best known for living in the branches of an ancient redwood in Stafford, California, for two years to protest a lumber company's plans to cut down trees in the area. We the Planet is organized by Hill's non-profit Circle of Life, which aims to inspire environmental consciousness.

Tickets go on sale October 10th, with additional performers to be announced in the coming weeks.
