Lots of good ones already. I fourth the Schneiders, and second the Truesdell Gil Evans Project and then might add,
Steve Lehman & Orchestra National de Jazz - 'Ex Machina'
Paal Nilssen-Love Large Unit -'Erta Ale'
Barry Guy's Blue Shroud Band, especially 'all this this here'
Martin Kuchen's Angles 10 - 'Today Is Better Than Tomorrow'
Fire! Orchestra - especially 'Echoes'
And everything by Rob Mazurek's Exploding Star Orchestra
