But even that one has the splendid "Bulgarian Bulge"!
And the whole rock/Indian/electric is often what retains my interest today. The "Hey Jude" on Fillmore goes beyond gimmickry into the realm of the genuinely warped, and the "Indian Lady" on Autumn is simply one of the greatest big band performances on record, period. In my opinion, of course.
Agreed, though, that the pop element started taking over, and that was...unfortunate. That and the elements of "gimmickry" (which, in this case, I'll define as a new idea not fully thought out/mulled over/etc and subsequently presented in nothing resembling an organic form) are rampant. But when it works, it works gloriously.
However, I don't have, but have heard, the later MPS Haiku, and it is pretty darn interesting indeed. Very organic, imo.
