Ghosts of Electricity, an all-star all-electric tribute to Bob Dylan, will perform at Mill Valley, CA’s Sweetwater on Halloween. The group features a number of musicians associated with the Grateful Dead family, including Mark Karan, Stu Allen, Mookie Siegel, Greg Anton, Robin Sylvester and Pat Nevins. The evening will also feature a costume contest (prizes include tickets and Sweetwater Cafe food) and “other spooky delights.” This is the rare opportunity to see Karan and Sylvester, two RatDog staples, share the stage this fall.
