I really like his playing. You say he's "not the flashiest", but it's his subtlety that appeals to me. I know the Bernstein/Stewart albums and "Time Is of the Essence". I must try to hear the Hall and Scofield.
As much as I love (and prefer) Wes, and as hugely influential as he was, I don't think he could ever equal Charlie Christian's influence on the evolution of guitar playing. Without CC, you might not have had Wes at all. You can't be a big influence on B.B. King and not be considered hugely important in the world of guitar music.
Saw Pat Martino last year. He sang the praises of Charlie Christian and played "Seven Comes Eleven". Seventy years after the death of Charlie Christian is what I call enduring influence!
