Blending hip-hop with funk, reggae, jazz, folk and rock, the undefinable group that is Michael Franti and Spearhead extends their outspoken stance on peace and social justice issues to sustaining our planet. Their annual Power to the Peaceful festival in Golden Gate Park this September should be a testament to the bands green-fueled staying power. Word around the campfire is that Franti's got a new album releasing then too, but for now, enjoy "Hello Bonjour" off the Yell Fire album and dream of grooves to come.

The Ditty Bops bewitch their listeners with iridescent golden harmonies, playful storytelling, visionary lyrical worldview and genre-defying tunes.

This track, Skinny Bones, is off their new self-released album Summer Rains, a special collectible cd package incorporating elements of storybook pop up and printed on recycled paper.

A green record label bringing you the "taste of fractured folk, infectious alt-country noir soaked in Americana," Portland's Stumptown Records got bit by the good green bug a few years ago. Today, the eco label utilizes 100 percent post consumer recycled packaging for all its releases, prints liner notes in non toxic soy ink, runs its fleet of vehicles on biodiesel, and sells only sweatshop free, organic free trade cotton merch. Two percent of profits from artists and bands are donated to environmental causes, so you can groove to this track from Kasey Anderson (hailed by Punk Planet as "one to watch in the alt country scene") with a clean conscience.

Co-founders of the San Francisco Bicycle Music Festival, SHAKE YOUR PEACE! dreams longingly of participating in a Critical Mass-style Bicycle Music Festivals rolling across multiple states with 80,000 feral music fans, 50 strong willed bands, and the hugest modular pedal-powered PA scene ever conceived, bringing music to far flung fields and scenic wild places.

Instead of rolling up in a car and rapping about cars, Fossil Fool  rides up on a bike, and raps about bikes.

The Ginger Ninjas describe themselves as "Mind shaking love groove folkfunk roots explosive mountain music for a pleasant revolution." Last year, they toured with fellow car-free folkers SHAKE YOUR PEACE! on a 5,000 mile odyssey from Northern California to the pyramids of Southern Mexico, exploring the frontiers of pedal-generated electricity, using their own bikes to power a hyper-efficient sound system. Originally conceived as a one-time adventure/statement/experiment, the band became addicted to low-impact touring, and now does so exclusively.
