Yeah, some of us are over 25-30 years old and remember concerts being, like $10 to $20, depending on your age.
I was talking with my dad about this just a few weeks ago. He's Gen X and could go and see a big name band for 10 bucks. I'm a Millennial and could do the same for 20. Even as a high schooler, I was able to afford to go see a couple of concerts every summer just on an allowance of a few dollars per week.
