Well
Speaking as one who gave up on the extreme end of the heavy metal genre when I stopped listening to Venom (or "80s Geordie NWOBHM band Venom") nearly 30 years ago I do wonder what any of this musical description means.
On the other hand, I did listen to a recent Skeptics Guide to the Universe episode where they played a very Beach Boys AI composition so I understand a bit of the technological aspect - which is where I would have been more interested in this article.
