Recently found this amazing performance on YouTube. Joni Mitchell, who’s guitar work is pretty good, with Pat Metheny, Jaco Pastorius and Michael Brecker on sax thrown in for good measure. Jaco has a solo spot at around 24, but it’s his accompanying playing that I think is so good. He seems to be using a fretted jazz on track 1 before switching to the more familiar fretless. Enjoy.
