Masterpiece? Really? I've had that one for about 40 years now, and it's pretty much the same handful of somewhat slight ideas over and over. He makes it all "sound good", but there's a not a whole helluva lot of filling in that pie.
As many as there need to be. Maybe more!
Also, as Konitz' time with the band goes on, you can hear the changes in his tone...it gets harder and brighter. Don't know if that was by choice, out of necessity, or a bit of both.
Lennie said it (Konitz' tone) was "ruined", and I can see why he would think that, but hell, Lee would go on to play with the Varitone, so, so much for that!
