Let's assume you don't follow the indie-rock blogosphere. You may never have heard of Mark Kozelek or his project Sun Kil Moon. Think of him as like an acoustic guitar-playing, folkie version of Trent Reznor; he's a brilliant musician who performs under the name Sun Kil Moon. It's a "band" in the same sense Nine Inch Nails is a band, but at the end of the day, Sun Kil Moon is Mark Kozelek.
I used to be a fan of his, but I am no longer. If you don't know who Sun Kil Moon is, you likely don't know why that is, so here's a little background on exactly why Kozelek may be the most immature, idiotic person in the indie world and why I can no longer stomach even his older recordings.
