I like Will Wood, his stuff has been described as "evil jazz", but it ranges from calm and soothing singer-songwriter type stuff to a full upbeat jazz band with chaotic composition and arrangement. I find his lyrics insightful, but they are also often quite abstract.
Cute girls doing cute things have some nice tracks, but many of them feel a bit the same-y.
The Vienna Clarinet Collection has great covers of classic clarinet songs, but classical and jazz.
I couldn't choose one, so here are a few jazz bands I like: Francis Coppieters, Loftys Comet, T-Square, Micheal Lowerstern, Archie Shepp, Sons of Kemet, and Mansur Brown
