I picked up an interesting DVD the other day- Lee Konitz live at the Vanguard
(with Roland Hanna, George Mraz and Mel Lewis). It looks like it was from around 1984, and the audio producer was Malcolm Addey (audio and video quality were excellent).
The big suprise was some footage of Konitz from 1954 with Warne Marsh, Don Elliott, Mundell Lowe, Billy Taylor and Ed Thigpen (plus a bass player who was unidentified). Good stuff.
Apparently this is part of a series- the box mentioned more becoming available soon.
Has this been discussed before?
