Indeed. I heard them at SUNY Binghamton fall 1973. Very intense, wonderful music. As I recall, it was one continuous improvisation that was nearing 2 hours...when, in the lobby of the building, right outside the concert hall, there was a shooting (a murder!). The alarms sounded and the building was evacuated. As we stood outside the building, I heard one person say to another, "that was the only way that concert could have ended."
Really? a shooting? I'm a Bing alum from 2005. Sounds like it will be a cool set.
