@stuartk: My original statement reads: "Most Jazz doesn’t speak to me". That was of course a generalization. Jazz music tends to not give me what I’m looking for musically, not as much as do other genres.
I listen for for and respond to first form: great chord progressions. melodies, harmonies, etc. The Jazz I don’t relate to is focused on other musical elements, predominantly the improvisational skills of the musicians. Yes, Bluegrass does too, but that is in addition to the other things I crave musically. Plus, as I said, Bluegrass instruments are more pleasing to me in terms of timbre than is most Jazz. Plus there are those vocal harmonies! A lot of Jazz lacks vocals; in a lot of my favorite music the instruments' primary contribution to the music is that of support for the vocals. Three is a lot of Jazz for which that is not the case.
Now, there is Jazz I like, names you would expect: Count Basie (man did his band swing!), Ellington, Mose Allison, Ray Charles, early Big Joe Turner, Cab Calloway. Composers including Irving Berlin, Bernstein, Gershwin, etc.
Early in The Stones career, Mick Jagger sang "It’s the singer, not the song". I very much disagree. Dylan once responded to a reporter’s demand that he define himself by facetiously characterizing himself as "A song and dance man". I’m not interested in dance, but am a song fanatic. Too much of Jazz treats the musical form as a mere excuse for the playing of instruments. Again, a broad generalization. The Jazz of which that is not true I like; that which is I don’t. I hope I succeeded in being more clear this time ;-) .
