I discovered U2 when I was in 7th grade. I had heard they were good, and I thought that socially it would probably be a good move to get into them. I asked a friend in my English class (whose brother was a confirmed U2 fanatic) to get me a mix tape of their best songs.
The tape was a winner. It had all the best tracks and even some deep cuts ranging from their earliest work up to Wide Awake in America. I listened to it at night while reading The Chronicles of Narnia.
Later The Joshua Tree was released and I purchased it on Vinyl. Rattle and Hum was the first CD I ever bought. Achtung Baby was the soundtrack of my entire senior year of high school. I think I listened to it at least once a day.
When I went on my mission one of the things I had a really hard time with was letting go of my music. I was afraid that I'd come home after 2 years of no popular music and find myself hopelessly out of touch with musical reality. (This from a guy who completely missed Pearl Jam, Nirvana, and the entire Grunge scene because he was listening to Mysterious Ways 10 times a day.)
Once, as a missionary, we had dinner with a young family who had a large Pink Floyd collection on display. The father of the family was a huge fan. My own exposure to Pink Floyd had been fairly limited due to my fear of anything remotely associated with long hair, black T-shirts, and drugs. (Bono's mullet notwithstanding.) But I knew that their Dark Side of the Moon album had broken all kinds of sales records, so we made conversation about it. I left there meditating on the sad state of people who stagnate on tired-out old bands. "Luckily for me," I thought, "I'm into U2 so that will never happen."
Tonight I went to see Arcade Fire. It was a great show. I have to say though, that a lot of douchebags have discovered them since I saw them play at Thanksgiving Point a couple of years ago.
