Heh. Yeah, I was just being silly.Max does that a few times in For Big Sid and I just can't hate on it
Reading through this thread, I think back to Miles' autobiography, where he described an argument with Bird, who said you could play a D in the fifth bar of a Bb blues (I think that was the scenario, anyway). Miles disagreed, but then at some point Lester Young did it (although Miles said he kind of bent the note, IIRC) and Bird gave Miles an "I told you so" look.
So I subscribe to the "There are no wrong notes" philosophy, as long as they're being played by a master who knows what s/he's doing. And this applies to cymbal sustain also, I reckon.
