How do you deal with bass players that speed up, I played wth a bass players thay sped up so bad that the beat turned around, and the leader turned around thought I was wrong and he never thought the bass player was at fault..
Usually it's bassists complaining about speeding drummers. There are a fair few conversations about that on bass forums.
Usually, if a player is off then I want to ignore that player and try to lock in with the most reliable musician (or singer). If the bassist is isolated then he's the one who will have to make adjustments.
While this runs contrary to the usual bass/drum marriage but I'd rather lock in with a solid guitar or vocal than chase an errant bassist around.
