The South Bay Experimental Flash
The South Bay Experimental Flash were a late 1960s Bay Area group, probably originally from the Richmond area. Personnel included David Ladd Anderson (saxophone/flute), Harry Critchfield (keyboards) and Kirk Harwood (drums). They shared the bill at the Fillmore with the Grateful Dead on November 8, 1969 and probably on other occasions.
it appears that the group did not release any recordings.
