Rolling Stone is premiering a recording of "We are the 99 Percent," a song from Rage Against the Machine's Tom Morello, Rise Against's Tim McIlrath, System of a Down's Serj Tankian and backed by the protestors of Occupy Wall Street. Morello explained the song:

It's our gift to the movement. I wanted to do a huge riff-rock anthem, It would feel like the excitement of the global Occupy Wall Street movement.
