This is a very busy shot and my eyes were continually drawn down to the crowd and the little girl with the popsicle rather than the musicians on stage. Perhaps tighter cropping around the musicians themselves?
Yep, this is live music but there's too much compositional clutter, it's hard for the eye to know where to settle. It does feel like a snapshot. I don't get much of a sense of what the music is like, or that this was a special moment above the rest of their show.
