That’s the Red Hot Chili Peppers playing at what we now call 123 Pleasant Street. This photo was taken by Randy Squeak Williams. He was the co-owner of what was then known as the Underground Railroad Nightclub. The photo surfaced as part of a longer discussion about an upcoming event at the club. Information about that event is available here.
Some awfully big music has come through that club during its long history. It’s possible though that this picture captures the biggest of them. Thank you to both Mr. Williams and Ms. Jeannie Kuhn for sharing the image.
