If you have a band you got to have 3 or 4 drummers and 3 or 4 bass players
That's one hell of band. I have drummed in many bands as the solo drummer, usually with one bass player, never two, and never another drummer except for maybe a little percussion added here or there by the guy with little to do, often the guy on keys or another guitarist. Nearly all the bands I listen to have one drummer and one bass player.
