Here is a story I told on a Slack.
When my mom was shopping churches, we went to a Korean church that was surprisingly depopulated. I think I was around ten or eleven at the time.
I found out that they had a schism over being loud about the gospel or something (I'm pretty sure I misunderstood), and a ton of people split to another church.

Anyway, the service was short, and the kids just sat around until the adult service was over.
One of the kids put in Exodus's Fabulous Disaster tape. Which I totally didn't get at the time. But later realized that was the first thrash I had ever heard.
