Would this be considered heavy metal?

[Bathoryswans]

This was recorded in 1969. Listen to the whole thing it gets really heavy towards the end.

 

[Baroque]

Yeah proto metal goes back to the 60's. But there's no link?

 

[Yelloweyedemon]

Time doesn't matter.

Queen had a thrash metal song, so anything is possible.

Also there is no video linked...

 

[Eligos]

Weird advertisement is way weird.
