In concert, jazz, and marching band, I was always grateful for the conductor as a visual cue for timing. All of that “dancing” often tells you where you are in the music or how you should be playing. I briefly performed in a rock band and tried using a metronome in my monitor to keep on beat. It was so much more difficult than I ever realized and I had to have a recording of our music played into my in-ear monitor so I wouldn’t get lost. What I would have given for a dancing possessed muppet rock conductor.
