I think Bostic has to be a lot higher. He was the most prolific of all the 50s guys as far as making his own records. He must have had like 20 albums on King. Loads of regional hits along with a few national hits, one being a number one R&B hit for 4 weeks.
Depends upon your criteria I guess.
Bostic and Culley I had originally as early rock, or pre-rock, sax players, since both straddled the dividing line in terms of years and style, but I just threw them on at the end when I posted it here so they'd be included. I agree, they should be higher. A big question is whether to include Illinois Jacquet, who many feel invented the entire style that emerged.
In case you don't have it there's a great four disc boxed set on Proper Records called The Big Horn: The History Of The Honkin' & Screamin' Saxophone
that has about a hundred tracks, arranged by the sax player's names, even if they weren't the featured artist, with a very informative booklet. Well worth picking up, though I'm sure you probably have most of the tracks, since they're 40's/50's only.
If you want me to co-edit it with you, I'd be glad to. I have so many projects up in the air now that my time is limited, but we could collaborate.
