San Francisco's Shiver
Basically, San Francisco's Shiver were a bunch of hard-rocking hippie freaks, brought together by a Texas-bred drummer who moved to San Francisco to take up where his obvious heroes Blue Cheer left off. They soon had a rather rough, tough reputation, playing Haight street fairs and Hells Angels biker parties. At one point they even had a singer with an iron hook for a hand, which he could use as a slide for his guitar, or for more violent purposes. Shiver played "heavy psychedelic rock" at its most primal -- no overdubs, raw as hell.
