I don't really have any major regrets. I was born the day before The Wall was released (feels cool mentioning it), and just few months before my favorite band, Iron Maiden, debuted with the self titled album in April 1980.
Discovered their music in 1995, didn't feel like going to their concert because I was still young and inexperienced, but I did see them in 1998 and I never missed a concert ever since, with two justificable exceptions (one time I was abroad for the Blind Guardian Open Air and the other time they played too far away from me on a working day in the middle of the holidays season, translated into "no extra days off from work, we're all locked and alternated with our vacations").
However, if I go back to my very initial line, I guess that SOME regrets can be found. Mainly:
- Savatage - didn't really pay attention to them, and so they totally flew under my radar when they played at a festival I WAS ATTENDING TO. I was there for Judas Priest. My cousin enjoyed all the show and eventually turned me to them. Obviously we all know that after 2002 they stopped making albums and touring
so I really wish I could have been a fan to see them at least once in their 2001-2002 last tour.
To elaborate better on this: the festival had TWO STAGES but in a closed venue, and it was hot as hell. There was a lot of traffic going in and out. We were all gasping for air. So when it was time for a band I didn't know - Savatage - to play, I went outside to catch some rest and some air. Had it been a normal open air concert, maybe I would have actually paid attention to their show.
- Alice Cooper - at least I did see him live twice, and his age doesn't matter, but I discovered him only in 2013. If he would have been part of my musical growth I could have had 20 years of concerts from him under my belt.
- Bruce Springsteen - started to listening to him only this summer. Why oh why it took me so long? had I been a fan, I could have seen them at least in 2016 or even 2013 in the stadium of my hometown. I've never been to a stadium concert because in Italy metal is still the devil's music or whatever and the only two bands that could realistically fill a stadium, Iron Maiden and Metallica, never got one. I could have seen Springsteen in a stadium.
