Why is that Miles' problem? I mean, I know where you're coming from, but doesn't it all come down to you not liking what was there more than there not being anything there at all?
Truthfully, I can say that about Big Fun (interesting production throughout - and that's "important" in its own way - but thin on the music overall), In Concert (group not yet together at all). & side 4 of GUWI (needed tightening up and/or editing and or no "Red China Blues").
Mileages are going to vary widely on this, obviously, depending on what in music gives you pleasure and/or stimulation. But it's that subjectivity that steers me away from the "Miles selling out" arguments, other than to point out that if the guy was just trying to get over, he picked a helluva strange way of going about it. I mean, Pete Cosey?
