When someone says Jazz or Swing, or Hot Jazz (if many non-collectors know what it really is), generally you'll have a variety of people you would think of first. Duke Ellington, Benny Goodman, Tommy Dorsey, and the inevitable Louis Armstrong. Though when I hear those genres, I'm more partial to another instrumental part of the advancement of all three genres listed. (Sometimes even unfairly so in comparison of others mentioned in the past.) That instrumental piece is of course the fabled pianist, arranger, and bandleader Fletcher Henderson. A man with a consistently changing sound, desirable roster of musicians, incredible discography, credited as one of the creators of swing, and has a great argument going for him having the hottest jazz orchs in the dance band era. Listening to his records are always a rewarding experience. His bands, when not under a vast amount of pseudonym, went under the standard "and his orchestra", His Hot Five, His Big Band, Connie's Inn Orchestra, and more titles. He also played for many bands including Will Bradley's, Joe Smiths, Bessie Smith's, Benny Goodman's (multiple, and frequently arranged for him too), Ethel Waters, and others.
