"Nobody knew more about the saxophone than Bostic, I mean technically, and that includes Bird." - Art Blakey
Coltrane told Down Beat magazine in 1960 that Bostic "showed me a lot of things on my horn. He has fabulous technical facilities on his instrument and knows many a trick." James Moody mentioned that "Bostic knew his instrument inside out, back to front and upside down."
