On Saturday, September 8th, Bob Weir will reunite with the rhythm section of his longtime solo touring unit, RatDog, as part of his performance at the annual Sound Summit. While originally announced as a special guest for the benefit, now, Bob Weir—a veteran of the one-day benefit concert—has clarified that he will perform with RatDog drummer Jay Lane and bassist Robin Sylvester under the moniker Bobby & The Chew Toys. Later in the fall, Bob Weir will reunite with Jay Lane for his highly anticipated tour with Bob Weir And Wolf Bros, also featuring bassist and famed producer Don Was.

The 2018 Sound Summit is scheduled to take over the Mountain Theater, a 4,000-capacity natural stone amphitheater, in Mount Tamalpais State Park this weekend. Sound Summit is organized by Roots & Branches Conservancy and raises money for its host park, with Sound Summit having raised nearly $200,000 in its first three years.

One of the major musical highlights in the Bay Area each year, this year, Bob Weir tops the Sound Summit lineup in addition to legendary jazz-funk artist  Herbie Hancock. Both legendary musicians share the bill with fan-favorite songstresses Grace Potter and Nikki Lane, in addition to ever-popular and soulful Con Brio.

Tickets for the 2018 Sound Summit on September 8th at the Mountain Theater in Mount Tamalpais State Park are currently on sale. You can head to the festival’s website for more information and ticketing.
