Though Charles Brackeen was born an Okie, he did play in Texas before moving out West. For whatever reason, I always put him in this category even though he's kinda been all over the place.
Here's my two cents, via Prince Lasha:
PL: ...Buster Smith was my director, and that’s where I got most of my stamina for playing the saxophone. It was so frightening standing next to him, because it seemed like the sound was coming up through the ground, up through the bottom of the horn and out through the bell. Being a young man, I was standing there [frightened] next to him for a couple of years; prior to that, we had jam sessions every Sunday in Fort Worth with James Clay, David “Fathead” Newman, and Leroy Cooper.
AAJ: That’s the Texas sound that you, Ornette, Booker Ervin and others have, where it just feels like it’s coming up through the floor, and at least from my perspective, out through the speakers. It’s a really forceful thing.
PL: I did the same experiment with Coltrane, Sonny Rollins and Eric [Dolphy], standing next to these men it seemed like it was coming up through the ground, up through the bottom of the horn and out the bell, and that’s one of the most mysterious, magical and frightening [things]. I stood next to ‘Trane that way, and next to Rollins that way (we worked in the Jazz Workshop, went to Boston; we were all over Chicago and at the Plugged Nickel, way before your days). Those are some of the things that used to take place, and this is why I suppose you’d said that about the Texas sound.
AAJ: It’s unmistakable for anything else, and it seems like you can tell where somebody is from by how they sound on their horn.
PL: Illinois Jacquet was from Texas too. There used to be a great player I traveled with named Scotty, and he could play with one arm tied behind his back — he really could play tenor, and he was from Houston also. Arnett Cobb, all those guys came up out of there.
