Katatonia? Opeth? A joke post I guess?
I could definitely understand those nominations tbh, even though i really like them both, there's this "formula" which almost every song follows.
This exactly. I think anyone who has heard Brave Murder Day or Discouraged Ones can agree that there are many songs that follow a similar formula. Later Katatonia albums also have a similar atmosphere running throughout. Opeth's songs sound similar in the way that most songs have growls, clean vocals, heavy riffs and acoustic parts.
EDIT: Many songs on the last Stratovarius albums with Timo Tolkki sound a bit similar.
A similar atmosphere running throughout an album means the album is well-constructed and flows well, ten times better than albums which are all over the place. And indeed Katatonia albums are like that.
Errr, wow.
That's a massive similarity indeed.
Anyway, if there are any doubts:
Katatonia - Consternation/Idle Blood
Opeth - The Grand Conjuration/Windowpane
Do I need to say anything else?
