I dunno how old you are, but I think I'm lucky for living in an era with good music and a strong enough economy for people to afford tickets to those good shows. Now it kind of sucks, and most bands are somewhat lazy, don't want to do live shows, as well as being some kind of puppets(so who can blame their motivation levels).
And rule #1, don't ever give a flat out no, when someone asks you to see a show, that you might object to seeing. Just go, because it's fun, even if you have to see something pretty lame. Your tastes will change, and in retrospect, those objected shows end up being great experiences.
I went to see the Boney M reunion tour. I had no choice, as I was dragged into going by a much older friend of mine! But I guess looking back on it, I can say that I saw a genuine disco performance. And I ALWAYS hear someone rip-off their music. Disco, but most(not all, they did some covers too) of it was extraordinarily original.
