The politically outspoken rap-rock band's lead singer, Zach de la Rocha, plans to announce Wednesday (July 21) that proceeds from a concert in Los Angeles on Friday (July 23) will go to organizations fighting against Arizona's law.
De la Rocha, guitarist Tom Morello, singer-songwriter Conor Oberst and United Farm Workers co-founder Dolores Huerta will also throw their support behind Sound Strike, an artists' boycott of Arizona.
Norteno superstars Los Tigres del Norte, Colombian rock singer Juanes, salsa-ska band Ozomatli and Puerto Rican reggaeton duo Calle 13 have signed on, along with Sonic Youth, Kanye West and Massive Attack.
