What kind of jazz (subgenre) does jazz24.org play?

Question

Been listening to jazz24.org for a while and I can't place what kind of jazz they play. It seems to cover a lot of eras but it's distinctive enough that I can almost recognize it from the music alone as opposed to other jazz stations.

Jazz comes in many subgenres. I'm not even sure if what they play is a subgenre. If there is some common thread please let me know. Here's a sample of their playlist:

• First Sample

Answer 1

This is no one subgenre, but there are definitely parameters. It's basically mainstream jazz of the years after Dixieland went out, but before smooth jazz was invented. There's a lot of swing, some Chicago style, some bebop, some Hot Club (gypsy swing). It's more small ensembles than Big Bands. There's a lot of vocals (but no scat), and some soul mixed in. There's a lot of newer artists, but only the ones who work in the traditional styles. It's basically all acoustic, upright bass dominates. There's some brass, and piano, but not much tuba or banjo.

There's no Louis Armstrong (Dixieland), no Kenny G (smooth jazz), no Monk (experimental), no Ellington (Big Band), no Ella Fitzgerald (scat). The Herbie Hancock is acoustic, not electric or synthesized.

That should be enough to get you pointed in the right direction in a good record shop.
