High Sierra 2011 Lineup Announced: My Morning Jacket, Neko Case, Ween

High Sierra can finally help itself to a six-pack of Sierra Nevada this summer as the event finally hits drinking age. The notoriously fun boutique festival has invited some equally fun guests to help celebrate its 21st birthday -- My Morning Jacket (pictured), Ween and Yonder Mountain String Band. They will be joined by anchor acts Neko Case, Warren Haynes Band and Rebelution.

Additional performers include indie rockers Dr. Dog, Dawes and Delta Spirit alongside such veterans as Maceo Parker, Ivan Neville and Bill Frisell, all fronting their respective groups. High Sierra favorites ALO will return for their umpteenth time, along with a newer Bay Area fave -- Beats Antique.

High Sierra takes place at the scenic Plumas Sierra Fairgrounds in Quincy, Calif. from June 30 to July 3. For tickets and additional information, check out the official website.
