Today, Sound Summit announced an impressive lineup for their 2017 event, including a very special Phil Lesh & Friends show featuring fellow founding Grateful Dead member Bob Weir, a solo set by Jim James of M Morning Jacket, and performances from indie rocker/actress Jenny Lewis, the legendary Preservation Hall Jazz Band, and San Francisco-based folk band Vetiver. The event will take place on Saturday, September 9th, 2017, at the scenic and historic Mountain Theater, a 4000-seat stone amphitheater which sits at the top of Mount Tamalpais in the California Bay Area.

Sound Summit is presented by Roots & Branches Conservancy, a group dedicated to raising funds for natural resource protection and conservation of Mount Tamalpais State Park and the surrounding areas. This year’s event is also sponsored by Birkenstock.
