This is Jaco Pastorius, the man widely considered the greatest bass player ever, doing a take on Jimi's Third Stone from the Sun. Jaco plays a fretless Fender Jazz bass -- '62 I believe. He famously ripped the frets out the night of a Weather Report gig. His hands were enormous, and he invented the use of bass harmonics for all intents and purposes. Jaco, like a lot of geniuses, became a manic depressive, self destructive drug addict who died young. My one question when I met Geddy Lee was about whether he had heard Jaco and he said he did and was amazed.
