Oh, man, here we go...
Those are heavy, heavy. And awesome. But the prevailing opinion of the guys who hung with Jaco at the time is that those solos, and many of his other standouts (Havona) were pre-composed, not improvised. IMO, it's reasonable to think that he may have played them a little differently night to night, but if Marcus and Berlin are right, Jaco had pre-composed the primary ideas in most of his solos.
Where these threads always turn sideways is that people seem to think that this fact, if true, suggests that Jaco was any less profound as a player. That's not the point to be made (IMO anyway).
The point is that the fact that Jaco's awesome solos were pre-composed versus improvised, again, if true, is a counterintuitive data point to most people.
By the way, while we're on this - what an excellent composer Jaco was!
