Locomotion Festival has announced Animal Liberation Orchestra and Dirtwire as the newest additions to its inaugural lineup. Set to take place on Aug. 2-4 at Roaring Camp in Felton, Calif., the newest sunny jamboree welcomes three nights of kickin’ California country and folk jams intermixed with arts and crafts. The latest acts join four previously announced performers, including three-day headliner The String Cheese Incident.

ALO, the Saratoga, Calif.-based improvisational rock quartet, and swamptronica electronic outfit Dirtwire will join the jam-filled, Golden State-centric lineup alongside the West Coast collective Brokedown in Bakersfield, featuring Nicki and Tim Bluhm, Lebo, Steve Adams, Dave Brogan and Scott Law. Additional festival performances include Bay Area roots-rockers Midnight North and bluegrass quintet Hot Buttered Rum. Through the course of the weekend, The String Cheese Incident will offer a total of six headline performances.

In addition to the Locomotion Festival, ALO is making a run of festival stops this summer including performances at Bend, Ore.’s 4 Peaks Music Festival on June 21 and High Sierra Music Festival in Quincy, Calif. on July 4. Dirtwire will follow its own summer festival series following the cumulation of a U.S. headline tour this spring. The electronica band will head into the summer season with performances at Electric Forest in Rothbury, Mich. on June 20-23 and at Winnipeg Folk Festival in Oakbank, Canada.

Additional artists for the inaugural Locomotion Festival are still to be announced. Early bird three-day tickets are on sale now. For more information, visit locomotionfest.com.
