It wasn't until about 10 years or so that I really cared to go to concerts. I'd been to some before that, but it was mostly a case of hanging out with friends more than it was going for the music. For whatever reason, I found myself actually wanting to go to some in the last decade or so and go to several a year now. My guess is, it ties into your question. In 2013 Merle Haggard and Willie Nelson came to Tuscaloosa for a concert. I had the opportunity to go, but passed. I regretted it almost immediately. Haggard, who is a mainstay on my playlist, passed away a couple years after that and I never got another chance to see him in person. Pretty much ever since then, even as much as I hate crowds and such, if there is an artist or band I like playing nearby, I'll usually make an effort to go. And I rarely, if ever, regret it.
