Keystone Korner, in San Francisco, was a jazz and blues club in the late 60’s till1983. It apparently moved to Baltimore in the 80’s, which seems weird. I was only 18 at the time this photo was taken so would not have been allowed in to listen. There is some disinformation online that the club didn’t open till 1972. I didn’t time travel to the future 2 years when I took this photo, so I’m convinced it opened in the 60’s. On the bill when I took this photo ( on a very cheap camera and scanned in to an iMac) is Boz Scaggs and Benny Cecil and the Snakes (couldn’t find anything online about Benny on multiple search engines).
