Chuck Mangione is something I would look into. Some pretty killer basslines in his songs.
And, more Weather Report. Can never have enough WR.
If we can go into other styles, check out progressive rock(Yes, Emerson, Lake & Palmer, Gentle Giant, Genesis, Focus, Comus, Rush to name a few). Many prog musicians are also accomplished players in the jazz field as well.
And, Panzerballet as well. New band, but a really good concept. It's jazz/metal fusion.
