I dunno luke, I'm quite in Awe of Miles Davis' performance on So What, and that song only has two chords. Well, actually, we're both right. You're talking about composition, and So What isn't an awe inspiring composition. However, the solos on it, particularly Davis' are incredibly melodic and beautiful, in a way that not many people were doing at that time (it was all bop with lots of hip chord changes.) For that reason I'm in awe of the performance, if not the composition.
