"The Slack" at the Beanery

This was kind of a trippy psychedelic band with two guitars, bass, and drums. They were pretty unstructured but the one guitarist, who is skinnier than in the picture, seemed to be good at coming up with strange lengthy solos consisting of chords sustained for extended lengths of time. He was talented, and the other guitarist had the riffs for "Back in Black" down perfectly, and he had an opportunity to play them when the bassist broke his low-E string and they took an extended break. The Beanery seldom has music featuring electric guitars.
