the LSD that became a seminal part of the "Red Dog Experience", the early evolution of psychedelic rock and budding hippie culture. At the "Red Dog Saloon", The Charlatans were the first psychedelic rock band to play live (albeit unintentionally) loaded on LSD. When they returned to San Francisco, "Red Dog" participants Luria Castell, Ellen Harman and Alton Kelley created a collective called "The Family Dog." Modeled on their "Red Dog experiences", on October 16, 1965, the "Family Dog" hosted "A Tribute to Dr. Strange" at Longshoreman's Hall. Attended by approximately one thousand of the Bay Area's original "hippies", this was San Francisco's first psychedelic rock performance, costumed dance and light show, featuring Jefferson Airplane, The Great Society and The Marbles.

The Avalon Ballroom, the Fillmore Auditorium, and other venues provided settings where participants could partake of the full psychedelic music experience. Bill Ham, who had pioneered the original "Red Dog" light shows, perfected his art of liquid light projection, which combined light shows and film projection and became synonymous with the "San Francisco ballroom experience". The sense of style and costume that began at the "Red Dog Saloon" flourished when San Francisco's Fox Theater went out of business and hippies bought up its costume stock, reveling in the freedom to dress up for weekly musical performances at their favorite ballrooms.
