Y'know, Hub Cap's not bad, Breaking Point I rarely pull out, (Night of the Cookers I NEVER pull out) but the rest of Hubbard's BN output is super-swell.
But to me, Sketches of Spain is overrated jazz, so what the hell do I know? I know that Open Sesame, Ready for Freddie & Blue Spirits kick Miles' ass in my little world.
Edit: Not only could Hubbard play better than most trumpeters, he could write circles around most other composers.
