this has been driving me nuts, I'm aware that BoC have recorded most of their drum loops themselves but I'm positive I have heard the same break, or possibly just a similar drum pattern/rhythm elsewhere, I have a hunch it could be from some late 80s hiphop tune. But the way I remember it is much slowed down, like this: http://puu.sh/jo1ZY/1d6a6ff36a.mp3

Anyone have any idea what I'm talking about?
