It’ll be like déjà vu all over again this Saturday (June 17) at Club Paradise, when the legendary San Francisco psychedelic blues band Big Brother & the Holding Company take the stage for a trip down memory lane. Of course, if you can remember the band from its early beginnings —in the Victorian mansion/boarding house at 1090 Page Street in the Haight-Ashbury circa 1966 —you probably weren’t really there, but Sam Andrew, Peter Albin and Dave Getz were, and they form the core of the band you’ll see Saturday. Missing from the lineup will be psychedelic guitar pioneer James Gurley, who is currently replaced by Dave Nieves. The role of Janis Joplin will be filled by Mary Bridget Davies, an Ohio based blues diva who has played “Pearl” in the musical Love, Janis. Tune in, turn on, and drop out for this show, if only to see if you can trust any band over 40.
