“At a young age, in my teens, I had to decide whether I wanted to buy albums or T-shirts,” Justin Anderson says. “I guess the narcissist in me wanted to wear the bands I listened to rather than have a record collection. I opted for the shirts and have been collecting for about 12 years.”

Anderson’s collection now runs approximately 225 shirts deep—90 percent of them black—and includes genres of music you expect to traffic in grim colors and outrageous designs of gloom: heavy metal, doom, psych, grindcore, thrashcore, and a slew of other “cores.”

The majority of Anderson’s collection comes straight from the bands, with the sale either conducted online or at a merch booth. And just because he’s smartly ditching out on the tees from his heavier years, that doesn’t mean he has plans to stop compiling.
