I happened to bump into this Jaco clip of Joni Mithell era which have stirred conversation about the way Jaco is playing behind soloists. Here's a couple of the most opposite, but also well-founded views on Tube of which neither is totally right or wrong or what do you think? "Actually, I find Jaco's playing on this brilliant and some of the best, melodic walking bass technique ever displayed. This is essentially a three piece group on this tune, drums, bass and sax. Jaco is not only laying down the bass but also outlining the chord changes. He does an incredible job doing all this, and throwing in all kinds of great chord substitutions to keep the harmony interesting and provide Michael Brecker with a great background against which to solo...." "As brilliant as Jaco's playing is on this, it's also obnoxious and totally self-serving, as if he just can't fight off his need to be the center of attention. He kills the tritone substitution too many times, and his playing at 2:04-2:07 and 2:37-2:41 is particularly annoying and pointless; stepping all over both the singer and soloist. Sorry folks but I am definitely someone who can appreciate his musicianship, but I would find playing with him to be a total friggin' chore."
