This (the 1986 Kolpinghaus solo) is really an amazing piece of art!
I think the difference between Jaco and other bassplayers is that, besides being a great technical bassist (e.g. playing fast using exotic scales) Jaco was also very very musical. Playing scales up and down is one thing, make music with it is yet another thing!
Btw I always wondered whether the Continuum intro (of Invitation) was a once only piece of music. Now I hear he played it in a bass solo years later. Great!
