With an unmatched focus on environmental sustainability, Pickathon Music Festival‘s only vice is some wonderful noise-pollution for neighboring Portland, Oregon. Taking place in Happy Valley, OR between August 5th and 7th, the indie-roots festival bypasses the normal list of festival regulars, to establish an eclectic family-friendly bill of banjo pickers, acoustic outfits, soul legends, and other bluegrass greats.

For its 13th installment, Pickathon already tapped Mavis Staples, Bill Callahan, Lee Fields & The Expressions, plus the Fruit Bats and others, and are now completing the lineup with 11 new acts – pushing the total near 50. Most notably, Black Mountain, Grupo Fantasma, and Wye Oak will be making the trek to the northwest, but the “Disneyland for music lovers” wouldn’t be complete without the sounds of Corrine West & Kelly Joe Phelps, Michael Hurley, Jesse Sykes & The Sweet Hereafter, L. C., Ulmer, Lightning Dust, Dawn Landes, Sunday Valley, and Eilen Jewell.

Tickets for the weekend will be available here beginning April 9th at 3 p.m. EST. In conjunction with Live & Breathing, the event’s promoters launched the The Pickathon Pumphouse Sessions, which features 2010 Pickathon artists like Dr. Dog, Breathe Owl Breathe, Little Wings, These United States, Langhorne Slim, Megafaun, and Fruit Bats performing in the secluded 10×10 pumphouse on the Pendarvis farm. The sessions can be viewed via the Pickathon blog.
