Not sure if this is the correct term, but I’ve heard drummers talk about playing at the rising or falling edge of the beat. I don’t mean constantly pushing the beat ala Copeland or laying back like Cissy Strut (or distorting the beat like J Dilla). You can clearly hear it in those cases. I’m talking about something more subtle that’s maybe done at points within a song. Is it useful? What does it feel like? Can a listener really sense this or is it just an imaginary conceit of a drummer?
