UK maybe?

I can’t pick just one band, however, I clearly remember the first time I listened to

• Black metal as a genre
• Aphex Twin
• Aenima by Tool
• Traversee by Year of no light
• Black Sabbath
• Industrial Rock in general and Downward Spiral by Nine Inch Nails in particular
• Hyperballad by Björk

I’m sure there are more if I think for longer.
