The solo on "Miles Runs the Voodoo down" on "Bitches Brw" shows a bluesy and funky side of Miles that you have to go back to "Miles Smiles" and the song "Freedom jazz dance" to hear previously, he had ignored that aspect of his style for several years. The "Jack Johnson"-album has some really inspired playing on Miles behalf as well but not much after that ; he mostly just blurted out a note every once in a while on "On the Corner" and those records.

Basically, I think the more "populist" musical idiom inspired Miles himself in terms of the solos etc. for a while but I don't think he had much of a vision for the music as a whole and I don't think he truly understood rock or funk either, several of his statements in his own book makes that perfectly clear... That's just my opinion though, everyone is allowed to disagree regardless of my tone...
