Rockers are getting into the giving spirit and generously donating their time to victims of October's devastating Superstorm Sandy. Pearl Jam singer Eddie Vedder and Foo Fighters frontman Dave Grohl, as well as Bon Jovi, have been added to the lineup for the 12-12-12 concert, which will benefit the Robin Hood Relief Fund's efforts for victims of Hurricane Sandy.

The one-night-only show will take place at Madison Square Garden, the "World's Most Famous Arena," in New York City on Dec. 12.

Grohl and Vedder join a spectacular lineup that includes previously announced performers like Paul McCartney, Bruce Springsteen, Kanye West, the Who, Roger Waters, Alicia Keys and more. Even more artists will be announced for this multi-genre bill, which features rock, pop and hip-hop acts.

Tickets go onsale on Monday, Dec. 3, at 12PM ET. The 12-12-12 show is helping the community and the nation come together to provide support to the Tri-State area, which was battered and bruised by the storm's winds, rain and power.
