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 DavisWhen I went in there, we used drum machine on "Time After Time" and "Human Nature".We don't use the drum machine to play a pattern. You play the pattern by being consistent.
