As we noted yesterday, Leftover Salmon will celebrate its 20th anniversary on December 31, 2009. The band is asking fans to send in photos, videos, music, art and other archival material (please direct inquiries to firstname.lastname@example.org).). However the group is in a sharing mood as well and is currently offering a free downloads of its mainstage set from this year’s High Sierra Music Festival. This seventeen song performance included guest appearances by the McCourys, Freed Haque and Vince Herman’s son Silas. This Sunday the group will perform at Denver’s Dancing in the Streets Festival.
