opeth are part of musical scene, a movement. to me, their music transcends much of the drivel that gets past around as death metal. i mean compare "orchid" to "altars of madness". both albums are different in almost every respect, but they have commonality. they are also milestones for the genre.
what i'm getting at is too many bands follow the pack, especially in america, instead of saying, 'fuck off. i'm doing what i feel.' i know opeth do that and as far as creatively slowing down, i don't agree. opeth have found their sound, since 'still life,' i think. you heard on 'delieverance' different things happening, and that's part of opeth's evolution. if it happened too much album to album, like atheist 'unquestionable presence' to 'elements,' i don't think i'd identify with them as much. and think about it, most bands don't jump around that much: iron maiden, judas priest, morbid angel, so on.
opeth is feeling and as much as that sounds pretentious, that's how i, and many others, connnect with it. end of story.
