The set of ten compositions (eight by O'Farrill and two by Stinson) brings up
the question as to what music in general and jazz specifically can be "about."
Although an abstract, ephemeral thing, music can range from completely abstract
(almost noise) where the building blocks (melody, harmony, rhythm) are almost
absent to the completely concrete where the melody, harmony and rhythm work
together in a completely predictable way (the tritest of pop music). Ease of
comprehension generally correlate with concreteness, but this does not
necessarily have anything to do with how much a particular person might "like"
the music.
