Agreed, both have artistic merit. In its context, I love Santana's playing. I can do without some of his more recent "star studded" efforts; but, still....
The parody runs deeper than meets the eye. There is more than a passing resemblance to "Evil Ways". Zappa's parody is in the same key (G minor) and the "chord orogreasion" is nothing more than a vamp between two chords (Gm and C) for the entire tune; just like Evil Ways. Hardly a "chord progression; and, that's the point of the parody.
