I like Deliverance. Earlier Opeth can sometimes wear me out - things happening all over the place, changing flow abruptly, pushing as many elements as they can into their songs. If im in the mood, sure, this is fantastic. But its also nice to have an (ironically) more laid back Opeth to chuck on, where you have time to take in the song development, where there is a stronger sense of continuity.
Wreath, though you might legitimately call it plodding and restricted (in a musical sense), is one of my favourite Opeth songs. Just such a different sense to it. Mock it if you want, and by all means praise Still Life...but don't for a second think that just because another album has 'more' it is necessarily 'better'.
ps. Don't think i hate Still Life. I love that too; i just think people are far, far too harsh on Deliverance, just because they wanted Still Life The Second - Zombie Melinda
