Got to reluctantly agree with you there, for the most part...
Cut date might be a bit late.
Just checked, and the last Phil Woods recording that I know of that isn't "jazzy" IMO is Red Garland's "Sugan," rec. July 1957.
Even at that, I can (usually) handle him up the point (early 70s?) when he returned from Europe and began becoming "iconic", which appears to have meant that whatever personal tension(s) had been driving his music was replaced by a self-congratulatory shower of alto-ism, where the differences between him & Bird became less relevant that the differences between him and Richie Cole.
