To anyone who disparages Miles' chops as a trumpeter, I challenge them to listen to "Right Off" (track one from "Tribute To Jack Johnson") and tell me that extended solo isn't one of the most brilliant they've ever heard.
In other periods of his amazing career he made up for his lack of athletic chops (ala Morgan, et al) with his sense of lyricism and timing. He played his horn with a high degree of intelligence.
His talents as a bandleader are unquestionable. The hiring of Cater, Williams, Hancock, and Shorter was a stroke of genius, serendipity aside. Of course one can make similar claims regarding his 50's bands too.
I would never express disdain towards anyone who doesn't "get" Miles, but I'll just say I feel very fortunate that I do.
