"Columbia marketed it for them old-time jazz people who couldn't get into what I was doing now in the first place. It was just a waste of time playing it for them; they wanted to hear my old music that I wasn't playing anymore. So they didn't like "On The Corner".
Miles was one funny "Dude". He spent 30 years of his life, and a lot of other people's lives developing his craft in jazz, and one day in 72 he decided to get into "rock funk" or whatever genre you wish to give it, and got an attitude when we didn't like it.
Why didn't he tell us, "Papa done got a brand new bag".
