Has it really been one year since a gaggle of union members, community leaders, hippies, anarchists and other impassioned activists took over a small park on the southern tip of New York City and thus started the Occupy Wall Street movement?

To celebrate the one-year anniversary of the start of the OWS movement and launch year two, a collection of musicians including Rage Against the Machine's Tom Morello, ex-Dead Kennedys frontman Jello Biafra and hip-hop duo Rebel Diaz have signed on for a concert set for Sunday (Sept. 16) at New York City's Foley Square. Morello announced the festival on the website for his Nightwatchman solo project.

My Brightest Diamond, alt-folk singer-songwriter Michelle Shocked, comedian Lee Camp, the Occupy Guitarmy and Cool A.D. of Das Racist are among the other artists on the bill for the event, which is part of an OWS Anniversary Convergence gathering featuring "three days of education, celebration [and] resistance." The Convergence runs from Saturday (Sept. 15) through Monday (Sept. 17).

Morello has taken an active role in Occupy Wall Street, leading peaceful rallies at various places across the country and teaming up with Ben Harper last spring for the tune ‘Save the Hammer for the Man.’ He also leads the Occupy Guitarmy, a group of hundreds of guitarists that marched through lower Manhattan during a May Day concert that also featured Dan Deacon and Das Racist.
