Congrats on the new guitar! I hope you love it and i hope it helps you on your guitar journey.
The first concert I can remember that I attended wasn't by choice as I was a child. We were on our summer family vacation and there was festival happening that my parents wanted to go to, and the two big bands that were headlining were Air Supply and Blue Rodeo. I can't remember any of the music that was played, but damn those snow cones being sold there were awesome
The first concert I went to willingly was Cheap Trick and Aerosmith along with other openers being Carly Rae Jepson, Flo rida, and Uncle Kracker.
