Jackson Browne, Alice Cooper, David Crosby and Graham Nash will perform in Tucson to benefit a charitable fund established after the shooting there that killed six people and wounded 13 others.
Other acts at the March 10 concert that Browne and Cooper announced this week include Sam Moore, Nils Lofgren, Keb' Mo', Jerry Riopelle, Dar Williams, Ozomatli and Calexico.
Astronaut Mark Kelly, the husband of wounded U.S. Rep. Gabrielle Giffords, plans to speak at the event, which will be held at the Tucson Convention Center.
It will benefit the Fund for Civility, Respect, and Understanding. Wounded Giffords aide Ron Barber started the fund to support people affected by the Jan. 8 shooting and to hold events promoting community unity.
"When I was in the ICU, I thought a lot about what it would take to help our community heal and unify," Barber said in a statement. "There was a huge outpouring of goodwill, kindness and compassion after the shooting, such a contrast to what happened that day. My family and I wanted to find a way to harness that goodwill to do meaningful things in the community."
