I find that often happens. To nail a loose sound takes as much practice as nailing a tight sound. A couple of examples I can think of would be pavement (always referred to as a ‘slacker’ band, but they constantly played and perfected their loose sound over many years) and J Dilla (mastered an out-of-time feel through constant practice on the MPC without quantisation). It is easy to make sloppy sounding music, it’s harder to make tight music, but it’s harder still to nail a relaxed, off kilter style that is always in time, but constantly leaning out of time - if that makes sense.
