What style of music would you cal opeth if...

On the one hand, it would be nice because I like Damnation. On the other hand, I would not like it because I really enjoy the songs/albums with an even mixture of death and clean vocals.

It would be very good and very bad. In a word - craptastic.

Damnation was an experiment, and I think a very successful one. But I certainly hope that it does not become the norm for future Opeth albums.
 
I'm asking because a friend of mine has been having trouble getting his heavy band together...apparantly drummers are a rare commodity...so he's decided to do it solo and try and do some lighter stuff sorta like Damnation. He wondered what exactly the style of music would be called.

Oh and sorry for the typos... when I typed it I was in a rush. :p
