I seriously don't know where to post this and I don't have much time, so please let me know where. Sorry, I'm kind of a noob here.
I wanted to recommend Impact Fuze for Jazz Fusion. Insane musicianship, crazy ridiculous time signatures, and a bunch of unexpected twists and turns with a punkish attitude. Check out the song Moscow
I would also like to recommend Break of Reality I guess for Crossover or Prog-Related. After seeing them live, my mind was blown. They are a unique band: they play with only three cellos and a drummer/percussionist. They cover prog tunes, classical music, and play their own really beautiful and haunting progressive pieces featuring a variety of chord changes, odd times, and many movements. Check out their cover of Tool's Lateralus.
Lastly I'd like to recommend A Perfect Circle for Crossover or Prog-Related. I was surprised they're not on here with their occasional odd times, various song structures, use of different instruments, thematic/conceptual lyrics, and atmospheric feel.
