Sometimes, if you ask people to "go downstairs and get me this or that," they'll say, "It's rainin" or "It might rain," or "There's some bumpy roads on the road," or bla-bla-bla. They give you all those excuses, so when they do something which is easy, you're supposed to say, "Damn, you did that?"
Miles DavisIf you make a suggestion and [musicians] don't know what you mean, you have to be able to do it yourself. I often sit down on drums and show 'em just exactly what I want. And I do it and then say, "How do you do that?" It's because I know how it looks, I know what I want to hear, and I don't drop or rush any tempo. It ain't in my body, it ain't in my nephew's body.
