I imagine it will be any CD that is not in any other Kategori fits of helplessness in the "Jazz" category classified. If this CD jazz music? I dont know; In any case there are wonderful interpretations of two outstanding musicians. Particularly worth hearing are numbers such as "The Moon is a Harsh Mistress" or the two pieces of "Cinema Paradiso".
Interesting for audiophiles: This CD is very well received, though the bass (well to play on portable radios) is a bit too heavily controlled.
The only thing that I have "criticize" to is the fact that I have not found any other comparable CDs more in a bass / guitar Instrumentation.
