Listening to Kenny Burrell, "The Tender Gender" on the Cadet label (related to the Chess Records label that released blues music):

While I don't recall seeing anyone post about this album, it is (to my ears) another great Burrell recording. It was recorded in 1966, but it looks like it might not have been released until the mid-1970s. I bought it used around 1980 - I knew of Kenny Burrell, and was looking for Chess Records blues recordings, so decided to take a chance on it (which worked out for me this time!).
By the way, I had the Yes album "Tales from Topographic Oceans" around that time, but sold it to buy blues records. I remember liking it, and thinking that it was very much like classical music (though I wonder if I would hear it the same way today).
