One of those guys I was always aware of but just never really got into. Knew about Traffic because of a guy in school who was into all kinds of Jazz and what passed off as 'alternative' in those days ... lol
But, now he just seems to really have it flowing through him in a different manner.
No doubt, it's effortless in that sense but I know what you mean. What I really like about guys like this is how they don't go off on weird tangents or get sloppy.
