First time I went to the Monterey Jazz Festival I saw Patty Waters (as well as another favorite of mine, Bobbe Norris). Patty's sound was so brutally honest and vulnerable, I was on the edge of my seat. I had known the ESP recordings, but this was more profound. I also noticed how much she got from Ethel Waters, and when I spoke with her she confirmed this. A few years later I got to see her reunited with Burton Greene at the Vision Festival.
I saw a Hendricks & Ross reunion at the Blue Note in 1999. The pianist, David (whose last name I can't remember), had been a classmate of mine in an abnormal psych class at Brooklyn College ca. 1974, but that was the only time I saw him gigging, and haven't heard of him since.
