The band will play the Hollywood Palladium on July 23 alongside Conor Oberst.

The concert will raise money for Sound Strike’s boycott of Arizona campaign, which both acts are involved with.

The campaign opposes the state's controversial new immigration law SB 1070, allowing police to challenge people they suspect of being an illegal immigrant.

Other supporters include Kanye West, Serj Tankian and Massive Attack.

Tickets go on sale on Monday (July 19) at 10am (local time).
