Hi m1469,
This is a no brainer for me. A performance with low/no musicality has in my opinion infinite mistakes. I have walked out on these when alone (or snored through them). These can be so passionless, so aurally boring. Where is the excitement? Worst case scenario is when I'm with friends who want to stay and I just tolerate the abuse of my ears and brain.
High musicality is more important for me on so many levels. I want to be moved emotionally. I want to be impressed by the tension, build up, rubato, crescendos, accelerando. I'm there to be entertained so entertain me. I want to feel something and come away richer from the experience. Maybe I'm moved to tears, laughter or I just close my eyes and let my imagination take me there. Note perfect just isn't going to cut it. If I have to have one or the other then I prefer a few mistakes and high musicality rather than the other way around.
Till next time, Joe.
