My top six:
Ben Webster
Colman Hawkins
John Coltrane
Stan Getz
Dexter Gordon
Gerry Mulligan
I don’t know why, I never got into Charlie Parker. His style just never appealed to me. I loved Ben Webster, tried to imitate his style when I was learning how to play! And, I will admit, my opinion on John Coltrane is almost entirely based on his “Ballads” album.
I'd really have to think about the other three. Stan Getz is great - the opposite side from Hawkins and Webster, but not sure I'd put him in the six. Dexter Gordon, I'd have to think about him or Sonny Rollins.
I'd give Johnny Hodges consideration - he's underrated. Consider Dolphy and Sonny Stitt. Lester Young would probably be one of them.
