It's February 2001, and I'm a senior in high school, and my home life really, really sucks (short version- abusive stepmother). Things were just falling apart, but I had always lived in a crappy home situation and didn't really have a way of conceptualizing it. I was just doing my time until I could escape to college.
I had recently started my journey away from radio rock music with the pop punk wave cresting at the time, but I was early in my journey. I had a Target gift card someone gave me for my birthday, so I decided I wanted to go buy a CD. For no good reason that I recall, I ended up leaving with Radiohead's Kid A. I get in the car, pop it in, and think that I must have made a big mistake.
Thing is, I only had a dozen or so CDs at the time, so I kept giving it a try, and I started to like this or that track. One day, I had to go to some early-morning meeting, and I put it in again. It was the pre-GPS era, and I got good and lost as the sun started rising, and "The National Anthem" was playing, and Thom Yorke is crying out "holding on!" as the song descends into free-jazz chaos, and it clicked. This wasn't music snarling at what's wrong with life, like so much of the punk I liked (and still do!), this was music that was down in the same trench as I was, next to me. Then, "How to Disappear Completely" came on, and "I'm not here / This isn't happening" just wrecked me. I pulled over and just watched the sun rise over the desert, and listened to rest of the album while trying not to cry and failing. I never made it to the meeting, but I had a new favorite album.
Within weeks I had the rest of Radiohead's albums, and had discovered stuff like Sigur Rós, Elliott Smith, and Built to Spill, and my musical life changed. I know it has a reputation for being a cold or distant album, but Kid A was and is an emotionally resonant album for me.
