One of the most controversial events in 20th century music history is when Bob Dylan went electric at the Newport Folk Festival in 1965. The folk figure’s decision to amp it up polarized fans and reverberated throughout the folk and pop music communities, and today those reverberations continue with all-star tribute outfit Ghosts of Electricity, who perform the music of Dylan with a fully electrified sound. Made up of local favorites Stu Allen, Mark Karan, Mookie Siegel, Robin Sylvester and Greg Anton, the band performs on Sunday, Aug 26, at HopMonk Tavern, 230 Petaluma Ave., Sebastopol. 7pm. $20–$25. 707.829.7300.
