In start of high school I really liked Arcade Fire's first two albums, stuff like Beirut and Radiohead. Then I was hanging out on an IRC channel circa 15 and got recommended Joanna Newsom and Xiu Xiu, and my taste started getting a little weirder from there—Van Dyke Parks, for his collaboration on Ys, and then into SMiLE, and freak folk, and Incredible STring Band
I at least got a crowd then, it was a good way to find good people. The hippies, the weirdos. Liking Merriweather Post Pavilion definitely made me some of the first friends I genuinely liked, at least after/since a breakup with my first friendgroup, back from middle school, where IIRC a central point of dispute was Mozart vs Rachmaninoff. Think I figured out I wouldn't get any girls with those friends—tainting through association and such, the scummy side of sociality—and cut ties.
I was a hardcore student athlete then—very near the top of my class, one of the best swimmers in the country for my age group. Very Protestant. Probably satisfied but not truly happy. Getting up at 4:30 for practice, lifting weights, swimming all afternoon after school. That music and the culture that came with it helped shake me out of that life.
