Now here is some really good music that you can definitely describe as jazz. The band is called "Steps Ahead". From Wiki
The group arose out of spontaneous sessions at Seventh Avenue South, a jazz club in New York City owned by saxophonist Michael Brecker and trumpeter brother Randy Brecker.[2] The first three albums were released under the name Steps, later changed to Steps Ahead, on Nippon Columbia in Japan, starting with the debut live album Smokin' in the Pit (1980), followed by Step By Step (1981) and Paradox (1982).
I listened to the live album "Smokin' in the Pit" in its entirety last night and it is what I would call "a keeper". Check out the personnel! Michael Brecker (arguably the best tenor player alive 1975 - 2007), and Steve Gadd, often placed on the list of "best drummers" on drums, Michael Mainiary on vibes, Eddie Gomez on bass, and Don Grolnick on piano.
The last 3 musicians are all excellent as well. All of them are superlative as soloists and there is great cohesiveness and "feel" among the band when playing as a whole.
I will be listening to them a lot more!
