In the case of Paul Motion, he's one of the few free players who very often will create a part that's not related to the person he's playing with, and in the beginning this might be off-putting, but on the other hand, if you're playing with someone like that, who's not accompanying you, but playing a parallel part, if you decide to change direction or do something other than what you're doing, you don't have to worry about having the drummer relate to you and catch it because, since he wasn't relating to you in the beginning, if you make a left turn, you don't have to worry about whether or not he's going to follow you or not, 'cause he didn't intend to follow you in the first place. It's very liberating - to have a player like that.
