The Danish Center being referred to as the "pico Acid test" makes no sense having been located at 607 S. Western Ave,Carthay Studios Is actually on Pico Blvd. (5907 W pico), The only Acid Test to take place on Pico as far as i can tell. I think the old "3 song danish center tape" which was often labled as "3-19-66 pico acid test" is exactly that. the Carthay Studios 3-19-66 Pico Acid Test. Calling danish center "pico acid test" is an old deadbase error that got propagated.
