For me, there is too much of a tradeoff.
While I love to watch the technical aspect of the music itself; I am a sucker for watching world class musicians play their instruments.
But just listening to the music, without the visual cues, allows me to get deeper into the music. I can just permit the music to wash over me, and transport me in ways that doesn’t happen if I am also watching. My focus is on the music, and not diverted to visuals.
