Ronald Darden is what I’d consider a pocket drummer. He learned to play in the church and you can tell that by listening to his solid funky groove. He’s a drummer forging out a musical career by hard work and perseverance
99.9% of drummers are working drummers playing small gigs, hauling their drum set around in a small car, having to pack it up, load it in, pack it back up and load it out themselves.
From my experience being a semi-pro drummer, playing an assortment of odd gigs in cramped spaces, I’m always trying to lighten my load.
