I find live performance to be very impressive, mostly in terms of pressure. Like, being able to play an instrument well is already a lot of time and commitment, but being able to do it on the spot with a bunch of people watching you requires nerves that I do not have.
I've seen a number of live performances by local artists (which I won't name because I don't want to publicise where I live lol), and I always enjoy them to some degree. I think there's some weird bias in my mind that makes me inherently enjoy music when in the setting of a live show. Like, to a degree, it feels more about the experience and the people around you than it does about the music.
