Occupy Wall Street movements throughout the world will participate in a General Strike on May 1 in honor of International Workers' Day (a.k.a. May Day). Das Racist, Dan Deacon, Rage Against the Machine's Tom Morello (a.k.a. The Nightwatchman), Immortal Technique, and Bobby Sanabria will perform during a rally in New York's Union Square, beginning at 4:00 p.m. More performers will be announced.

Morello will also lead a "Guitarmy" of 1,000 guitarists, string players, and singers that will march from New York's Bryant Park, through midtown Manhattan, down to Union Square, culminating in a performance at 4 p.m. An open rehearsal for the performance will begin at 12 p.m. in Bryant Park, to practice Woody Guthrie's "This Land Is Your Land", Sergio Ortega's "El Pueblo Unido", Willie Nile's "One Guitar", the Nightwatchman's "World Wide Rebel Song", and the traditional protest song "We Shall Not Be Moved". Anyone is welcome to participate; learn more about the Occupy Guitarmy here.
