Interesting to imagine what would have happened if Miles had gone with this complex composition route in his electric period rather than the long, minimalist vamps.
I know what you mean, but I don't think it's as simple as that...check this out: http://www.plosin.com/MilesAhead/CodeMD.html
I sorta scoffed when I first read this information (in a bootleg's liner notes, actually, albeit without the larger overview provided here...but with specific references to the music on the recording itself), sounded like retro-fitting to me, but have come around with the hearing of more and more bootlegs. The markers are definitely there, and the effect is one or composition, rather large-scale, actually...not unlike how sonny would play these longass sets that would ramble from one tune into another but ultimately make set into a suite. In Miles' case, it was the other way around, he'd make a suite into a set.
Was not contesting that... but for a little bit in late 1968 and early 1969, there was complexity introduced WITHIN compositions that Miles recorded. I also didn't mean "long, minimalist vamps" in a negative way - I like Miles's 1970-75 music a lot.
