Opeth. *ducks*
Seriously though, it is almost unheard of for bands to exist for 20 or more years, and write 9 albums without having made a bad album, or something that is so run of the mill that no one gives a shit about. Opeth has never done this.
With Opeth it's pretty relative. Everything is run of the mill compared to BWP or SL.
The overrated will always be overrated and the underrated will always be underrated.
Not even. While I hold Still Life above the rest, to say BWP is that much better than MAYH and Deliverance, and to a certain extent Morningrise, is just lunacy. I'm not going to go and rank all of their albums, but there's no way you could ever convince me or anyone who actually knows Opeth's discography that they only have two great albums and then the rest of their material. No way in hell.
For example, what do you think of your countrymen, Threat Signal, WAIF?.
Fuck i gotta agree with chimaira.
They definatley have produced some crap, but mainly early on. They have also produced some incredible albums too.
Volbeat are also super-fuckin-popular over here right now, but that's cool because they are clearly 100% more badass than Opeth ;D
