This explains how one can have too much pocket. It allow points out that pocket and groove are two totally different (yet intertwined) things.
Here is an excert from Modern Drummer Magazine-March 2006 issue (Bozzio cover). This is from the "Pocket Monster" himself, Michael White's interview (taken from pg 88):
MD: So how does one learn to groove? If you were giving a lesson to someone who wants to do what you do, what would you tell them?
Michael: The first thing I would say is that everybody has an inner clock. You have to get in touch with your own body clock. If you're playing and it's not making you move, or if you have to break your "sway" to do a fill, something's not grooving. You should have a certain strut about your playing, that strut should never change, whether it's a fill, a break, or accents. That strut should always be there.
People get nervous about click tracks. Playing to a click track is quite different fro playing with a loop. Young kids can play great with loops. They ride on the loop and do all sorts of craziness. But with a click, you have to make it work for you. You have to make the click feel good. It's just a machine, so you have to play around that click and make it feel like it's got a hump to it.
Sometimes people play with clicks and it feels stiff. The tempo might be right, but it's not grooving. It's too straight. Being in time and having a groove are totally different things. In my opinion, you have to be committed to the groove.
