blackletter in heavy metal bands

Hello.

This is my first post, I hope you can help me.

I'm making an typographic investigation about the influence of blackletters in heavy metal bands.
I've found some information but I need something specific about how was that influence and why, there's a lot of heavy metal bands like Motorhead, AC/DC and more where they use blackletter on their album covers.

There's some examples. Thanks!
