Just a quick glance at the Big Band genre in my ipod:
Anat Cohen - Noir
Arturo Sandoval - Dear Diz
Bill Watrous & Pete Christlieb - Kindred Spirits
Clare Fischer - Pacific Jazz
Count Basie - 88 Basie St.
Dave Grusin - West Side Story
Duke Ellington - ...And His Mother Called Him Bill
GRP All-Star Big Band - All Blues
New Orleans Jazz Orchestra - Live!
Phil Woods - Groovin' To Marty Paich
Rob McConnell & Boss Brass - Brass & Woods
The Tonight Show Band - Vol. 1&2
The Vanguard Jazz Orchestra - Up From The Skies
Wayne Bergeron - Plays Well With Others
....and these were only a FEW of the highlights! And don't get me started on 'little' big bands (nonets, tentets, etc!). Love that horny music!
