I think Jonathan is referring to the Half Note recordings from 1959 (Konitz/Marsh/Evans/Garrison/Motian) - some was released in full on a Verve twofer CD in the 90'sThe LP releases on Revelation 22 & 27 (The Art Of Improvising, Vols 1 & 2) were just the Warne solos with rhythm section plus the occasional Konitz I have what I believe is an "unauthorized" release with 12 of the complete Half Note takes. I understand there are more than 40, so I'd buy it to get the other 30.
