Agreed. I don't think we sound much like Opeth, and even Mike has said he doesn't think we sound like Opeth. We have some basic similarites to them and I think we can sometimes appeal to a similar fanbase. Opeth have a very unique style and sound to them, I don't really think anyone out there sounds closely like them.
Alot of bands who are compared to Opeth are being unfairly called "rip offs", too. Opeth are fantastic but they didn't invent the wheel folks, alot of other bands were doing similar stylistic things before (or started around the same time as) Opeth.
And Enslaved are an excellent band, I agree! But I wouldn't really compare them to Opeth either, again other than in some very general ways.
