I know how he feels. I'm a musician too, and it's really demoralizing when you're up on stage rocking your heart out for people, and you look out and see people's noses in their phones rather than listening to you. (It's probably more demoralizing when you're a tiny indie band playing for fun rather than professionally, and there are only 20 people there and the only reward you get is the chance to play for them.)
