The musc as art debate is not worth getting into and is also pretentious. Bostic was a great player and if he had to get a bit commercial to survive, so what (very players could make a living playing jazz). His Gotham material is my favorite, though I also like his King material and the later stuff he did with Joe Pass. Not many alto players could make that extra octave that he could. I wish I could have seen him but was too young when he played in New England and of course as a teenager knew nothing of R&B. It is a shame he did not live longer as he might got a chance to make more albums like the Pacific Jazz lps, but I am satisfied with his recorded legacy including his King lps.
