Sometimes [playing free] doesn't happen, because maybe a guy's wife'll come in, you know, and his ego will catch him. If everybody's completely just straight-without any old ladies over here, a fourth of whisky over there; if it's balanced right, it'll come off. It has to be. But when you get egos involved with playing free, you can't do it.
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.
