Tom Morello is living proof of the transformative power of rock 'n' roll. As the co-founder of Rage Against the Machine, Audioslave and Prophets of Rage, and through collaborations with everyone from Bruce Springsteen to Johnny Cash, he has continually pushed the limits of what one man can do with six strings.

"I've been devoted both musically and as an activist to fighting injustice at every turn," says Morello. "Amid this heightened sense of impending doom, it's now time to rally the troops in a last-ditch effort to save the planet, and our artistic souls. By challenging the boundaries of what music is and has sounded like before, you can open peoples' eyes to changing the status quo in society."
