I recently came across a poster or handbill for the 2/25/66 acid test http://www.deadlists.com/posters/1960s/19660225.html
The information on that says the venue was Cinema Theatre on Western Ave in LA Under comments the deadlists entry says, "Owsley "Bear" Stanley: ...the Sunset Blvd. test was 25 Feb." Was there a different test on Sunset Blvd or perhaps the venue was moved from Western Ave to Sunset Blvd? As an interesting aside I found this on a general theater website (http://cinematreasures.org/theater/2231/): "The last time I went to the Cinema was in the late 1960's, to see "Don't Look Back." I got the feeling that the people running the place had dropped acid. The tidy, European atmosphere was gone, and the subdued colors of lobby and ticket area had been replaced with a sloppy coat of lurid, day-glo orange paint. The place went rapidly downhill after that, and was showing x-rated movies within a couple of years." Iver
