I don't live in an area where I can easily attend lots of concerts, which is sad. Though to be fair, I could probably go to some if I were to make an effort, but it depends on which acts are nearby and what day of the week the show would be. Often taking off work to drive there and back is not possible.
That being said, my most memorable one was when I lived in Japan and went to Tokyo one weekend to see Rie Fu perform. She is a Japanese singer-songwriter, but at the time was attending university in London, so her songs were a mix of Japanese and English (anime fans may recognize her from
Life is like a boat.) I knew I liked her style of music and decided to attend her concert.
It was a bit of an adventure in itself just finding the location (and I still remember the subway's terminal stop being on the third floor of a department store. Is this normal for subways?) Also, while I learned some Japanese while I was over there, I was never great with my listening comprehension. So it's not that I could understand a lot of the non-English lyrics. But I didn't need to understand them to enjoy the music.
My only regret is that I had to leave without attempting to get an autograph, but I'd already noted the time the last bus left and didn't want to risk it. Not really adventurous of me since I could have walked back to the subway station, but it would have taken about thirty minutes and I didn't trust my directional abilities.
On the bright side the bus driver was very polite to not pull away from the stop when I stood at the timetable with the question "Is this the right one?" probably written all over my face. (It was. The right stop, that is.)
Anyway, it was one of my favorite experiences as I was living there. So all in all I'm glad I went.
