This is audio only and not the best quality, but it is some of THE best Jaco playing I've ever heard and it was at a time when many thought he was on a downslide. He did a clinic at a small school in Martinique. It is just Jaco and Rashied Ali on drums. I saw this combo once in NY and it was HORRIBLE, but at this clinic, it was great. For those who don't know who Rashied Ali is, he is the drummer who replaced Elvin Jones in Coltrane's band when Trane got more into the completely free thing. They do things like Broadway Blues and some other things and at amazing tempos. Check it out.
