Bruce, you are right .. Konitz has put out a lot of albums, BUT, most of these have been in the last thirty years. For those of us who were Konitz fans dating back to 1953 (when, as a 13 year old, I received as a gift of a 10" Prestige album of his) it was a long wait between albums. A look at his available discography in the period up to the late 1960's shows a relatively small number of albums for a musician of his stature at the time. I distinctly remember buying both of these LP albums at Sam The Record Man's store on Yonge Street in Toronto at the time they were released. They were incredible additions to my then small, but treasured collection of Konitz albums. I have both now on Japanese CDs and they continue, as Larry pointed out, to bring me great pleasure.
Happily, they are bringing me pleasure too, now.
You're right of course. I've gotten the impression that I could actually collect all of Konitz's 50's/early 60's output with a little more trying.
