I have to admit, until I read his obituary, I was unaware at the breadth of his playing. I thought he was a straight-up jazz guitarist. What an incredible discography: https://www.discogs.com/artist/268217-Phil-Upchurch?superFilter=Instruments+%26+Performance. He played with so many artists across genres from jazz to blues, from funk to rock, from R&B to gospel... even multiple Christmas albums... he was there.
Decided to break out the 4 disc Steven Wilson revisit of Yes “Tales from Topographic Oceans” and listen to cd 3, the alternate version of the album using studio run-through and live material. Wow. A great experience with the stereo in it’s current form. Love this music!
