As previously reported, Sweetwater Music Hall in Mill Valley, CA, will host a benefit for John Perry Barlow, the poet and political activist who also has acted as lyricist for Bob Weir and the Grateful Dead, and now more guests have been added to the all-star lineup, including some members of the Grateful Dead extended family and more.

Steve Kimock, Jeff Chimenti, Wally Ingram and Robin Sylvester are now a part of the benefit, and String Cheese Incident members Michael Kang, Michael Travis and Jason Hann have also been announced. They join Weir, Les Claypool, Jerry Harrison, Lukas Nelson, Ramblin’ Jack Elliott and Sean Lennon as announced guests.

The benefit, which takes place this Monday, October 24, will feature live music at Sweetwater, along with live and silent auctions. Money raised will go toward the medical fund of Barlow, who has suffered medical issues throughout the past year and a half, including a heart attack in late May of last year.
