Phil Lesh will offer a very special set at Newport, RI’s annual Newport Folk Festival this Friday, July 26. The Grateful Dead bassist has already confirmed that his Terrapin Family Band will be joining him on the Newport stage, but Lesh will likely embrace a bit of the 60-year-old festival’s trademark hootenanny spirit.

A number of musicians in Lesh’s orbit are slated to perform at Newport Folk on Friday, including longtime collaborator Warren Haynes, recent Friend and Heartbreakers keyboardist Benmont Tench, and Lukas Nelson, who has spent part of the summer on the road with Lesh and his Family Band as part of the Outlaw Music Festival Tour. Kacey Musgraves and Sheryl Crow, Americana performers who draw from the Dead’s rootsier side, are also confirmed to play the main Fort stage before Lesh.

The bassist is the first surviving member of the Grateful Dead’s core lineup to perform at Newport Folk in over 20 years, though Bob Weir & Rob Wasserman appeared at the legendary festival in 1995. Songwriter Robert Hunter also made a Newport Folk appearance in 2014.

Tomorrow’s opening-day lineup also features Amy Ray Band, I’m With Her, Liz Cooper, Yola and Terrapin Crossroads regular Todd Snider, among many others. Later in the weekend, Lesh will move to The Peach Music Festival in Scranton, PA, to perform with a group of Friends that includes Haynes, John Scofield, John Molo and Holly Bowling.
