Leftover Salmon in Tucson

Leftover Salmon is an American band formed in Boulder, Colorado, in 1989. The group plays improvisational bluegrass shaped by rock, country and Cajun music, a style it has called “polyethnic Cajun slamgrass.” Its best-known records include Euphoria, The Nashville Sessions and Bridges to Bert, while “River’s Rising” has remained a central song in its repertoire. In 2007, Leftover Salmon reunited at the Telluride Bluegrass Festival after a hiatus. The band then resumed sustained touring, including hometown concerts at the Fox Theatre and performances at Red Rocks Amphitheatre. Its concerts feature a full band built around Vince Herman’s guitar and Drew Emmitt’s mandolin, supported by banjo, bass and drums. Songs are frequently extended through group improvisation, linking bluegrass picking to the open-ended structure of a jam-band set. Festival appearances have also included repeated performances at High Sierra Music Festival and Northwest String Summit.

Keller Williams is an American singer-songwriter and multi-instrumentalist born in Fredericksburg, Virginia, in 1970. He plays acoustic jam music shaped by folk, funk and bluegrass, and is known for the song “Freeker by the Speaker” and albums including Freek, Laugh and Dream. The String Cheese Incident joined him on the collaborative album Breathe. Since the 1990s, Keller Williams has toured as a solo performer and with several band projects. His festival history includes Bonnaroo and the High Sierra Music Festival, while his ensemble work has included Keller Williams with More Than a Little and Keller Williams’ Grateful Gospel. His solo concerts are built around live looping: he records guitar, bass, vocal percussion and other parts onstage, then layers them into complete arrangements. Keller Williams’ Grateful Gospel shows apply a gospel-influenced ensemble format to songs associated with the Grateful Dead.
