Perhaps goosed a bit by the additions to the Bonnaroo line-up which were just announced, the High Sierra Music Festival has confirmed its initial roster of artists. Performers include Yonder Mountain String Band, Karl Densons Tiny Universe, Keller Williams, Garaj Mahal, Tea Leaf Green, New Monsoon, Maktub and Man vs. Machine (which will feature James Blood Ulmer, Jamaaladeen Tacuma & Calvin Weston). The festival will return to Quincy, CA on June 30 through July 3rd.
