if u think gothic themes and songs about mental insanity with punching rhythmic drive only happens in death metal, think again.

there are lots of folk/americana/country/celtic gothic bands but COMUS is the grandpa of them all...

they're not so popular among rock bands but they have some following among folk/americana/country fans.

but one rock band who revered them like gods is OPETH who covered their song Diana and talks about COMUS on live shows
