Now that I have the Properbox, I note a couple other missing masters. An alternate of Supersonic from the 10/23/47 Allegro/Royale/Savoy date is missing. Also missing is the rest of the Metronome All Star date. Two songs (Victory Ball and Overtime) were recorded at the time AND they did 10" versions as well as 12" takes. All 4 have been reissued in various packages. Bruynincks lists a third take of Victory Ball I've never knowingly encountered.
The box does include the contents of 2 records issued by Jazz (Tristano family label), Live at Birdland 1949 and Live In Toronto 1952. They do not include the other Jazz record (Wow), which falls into the time frame of the set.
Ethical issues aside, this is a very useful and intelligent set. The transfers are ok.
One discographical note - they repeat the mistake of listing Shorty Rogers as the trumpeter on the 1945 Emmett Carls date. The player was Marky Markowitz.
