I'm a huge Jazz fan. Have been for years. I listen more to the early, early shit. Hotjass, Ragtime, Hot and Sweet Jazz, Early big band/swing, early Tin Pan Alley and novelty music. I'm all about it. I'm hugely into Gypsy Jazz.
Django is the fucking man.
Louis Armstrong, Original Dixieland Band, King Oliver, Bessie Smith, Jelly Roll, Fletcher Henderson,
Duke Ellington, Benny Goodman, Count Basie, Art Tatum, Chick Webb, Bix Beiderbecke, Annete Hanshaw, Artie Shaw, Billie Holiday, Chet Baker, Dinah Washington, Dizzie Gillespe, Ella Fitzgerald, Gene Krupa, Glenn Miller, Josephine Baker, Louis Prima, Oscar Peterson, Scott Joplin, Sten Getz, Tommy Dorsey.....
I also listen to allot of newer acts that play these styles well.
Janet Klein, Bernadette Seacrest, Stolen Sweets, Shit, Squirrel Nut Zippers got lumped into that whole swing revival back in the mid nineties, but they are actually closer to Django's gypsy jazz than anything, and they are a truly great band, especially the first three albums.
Also Leon Redbone, and a huge amonut of Tom Waits catalogue skirts one or more of these styles at the same time.
KOH/Balls deep in old music.
