A couple of points to add to your informative review. This issue is depressingly illustrative of the all too common sloppiness of record companies.
1. Why not issue the albums in chronological sequence and follow Django with Concorde - all from 1953 to 1955 - it then would not have been necessary to omit two of Concorde's tracks - namely Concorde (of all things to omit!) and Softly As In A Morning Sunrise.
2. You could then start disc two with Fontessa from 1956 and add another album - No Sun In Venice from 1957, the wonderful album that was not given a name from 1957, Odds Against Tomorrow from 1959, Pyramid from 1959/1960 - I could go on but you get my point.
You can perm any combination of these albums and easily fit two on one CD, but, let me repeat, why not do them chronologically?
However, thank you for your input.
A correction to this post - I have now received this album and can confirm that the missing tracks are, in fact, not missing - they are just not listed by Amazon.
However, my main point about couplings still stands.
