Grammy-winning guitarist Tom Morello is the latest addition to this year's Tempe Music Festival, which will be held April 3-4 at Tempe Beach Park.
Morello, who's played with Rage Against the Machine and Audioslave, was named the 26th-best guitarist of all time by Rolling Stone in 2003.
Since 2003, Morello has been performing politically-tinged folk music under the alias The Nightwatchman.
Morello will be added to the Tempe festival's Saturday lineup, which already features Mutemath, Shiny Toy Guns, The All-American Rejects and 3 Doors Down.
One more act is expected to be added to Saturday's roster.
Friday's lineup will feature The Outlaws, Cowboy Mouth, Roger Clyne and the Peacemakers and Kid Rock.
Festival tickets went on sale this morning. Several thousand early-bird tickets are available for $25. After they're gone, tickets will be $35 in advance and $45 day of show.
