And, in fact, there are plenty of folk who go to live music events because they want to be at a live music event, not caring too much about who is performing. This is particularly true at the bottom end of the market: go to any show in a major city in a 200 - 400 cap venue and you'll have an audience of people many of whom are more interested in instagramming and being able to tell their friends that they "saw this really cool band in this totally underground venue".
