I did a choir gig recently. Two keys players, one kit and me on bass.
The conductor wanted the pianist to just play a rhythmic pattern above middle C. The kit/bass section were laying down a solid groove. She tried 3 times, but was still playing something an octave + below middle C to give her something to syncopate against. The conductor said 3 times "no, just the rhythmic thing". Eventually, I put my bass down, walked over and told her to play it again. I held her left hand and lifted it away from the keyboard and the magic happened. To make it EVEN sweeter, I have been waiting 42 years to do this with this specific player.
Keyboard players are clueless. Ones who actually understand a band dynamic/make up are like gold dust.
