I saw Miyavi, who is a Japanese guitarist, rock singer, three times. Each time I was blown away by it and had a wonderful time. The most remember-able concert was the last one about three years ago. I was lucky enough to get right up against railing and when he leaned over the stage, I managed to touch his hair. I fangirled like mad. Not gonna lie.

OH MY GOD! i'm so incredibly jealous of this! In middle and high school i was a huge j-rock junkie and Miyavi was one of my favorite artist. Lucky some time that year i went to a convention where Psycho le Cemu was playing and that was a pretty good time since i loved that band as well.
However, i dont know if i could really pin-point a super memorable "concert" i've been to since i've only been to so many. However three years ago my favorite band, Lemuria, was playing at a dive bar on my birthday and my partner arranged it so they would wish me a happy birthday before they started their set along with buying me some merch. On the way home he explained that he originally asked the band if they could "ask me to be his girlfriend," but got kind of scared out of the idea and thought maybe we werent ready for that yet. While that would have made the night 27083742087308x better, the happy birthday was enough for me!
