What Genre Is Opeth?

Opeth is in a class all their own, no definable style or genre. They are a force unto themselves.

Quit trying to pigeon hole.
 
Many metalcore bands use "death" style vocals...it doesn't make them death metal...death metal has to do with macabre subject matter as well...not just fast drums and growling vocals.

The genre thing is ridiculous...you can classify yourself and alienate a wider audience.
