I've been a huge Opeth fan for many years, and Ghost Reveries tops my list. Through Mikael and Steven Wilson, I've gone on this fascinating musical journey back to the 70s to bands I never knew existed - Scott Walker, Mahavishnu Orchestra, Blackwater Park, Vangelis, etc. etc. - and this album feels like an honest, authentic tribute to those influences. Mikael has a fantastic singing voice, and I love his mellow music even though I'm a metal fan. This is like Atonement from Ghost Reveries, my favourite song. It's so nice not to hear him screaming but instead using textured vocals, acoustic instruments, keyboards, etc. To me it feels like an album that draws from his influences without any concern for what the metal community would demand of it.
In short, this is the Opeth I like, the prog, acoustic, mellow, complex, thought-provoking Opeth - not screaming metal Opeth. So if you're looking for screaming Opeth, this album is not for you, but if you want profound, thoughtful, philosophical Opeth, got get it. It's my #2 Opeth album next to Ghost Reveries.
Plus, it's the coolest album cover ever!
