this one is one of the coolest threads ever.
well, i'm not really sure if Omnio is a concept album per se, but it seems to me that it is, so, here we go:
In The Woods - Omnio
could be about, erm, meaning of life? throughout a lifetime perhaps.. like, from the spring and summer bloom [299 796 km/s would be the birth, I Am Your Flesh the struggle within and the Kairos! the indefinite questions?], to late autumn [Weeping Willow] and winter/ending of a lifetime, reaching the "omnio".
the second one i'd like to mention is
WASP - The Crimson Idol
the rise and fall of a rock star. that record means so much to me.
i also know that The Crimson Idol is much influenced by Quadrophenia by The Who, but i haven't checked out that one yet.
nice observations you guys gave on Seventh Son, or Oceanic [i had some other interpretations myself, but that's the beauty of it, right?
]
the only record i really liked by Dream Theater was Scenes From A Memory, probably because it was a conceptual [and rather obvious one].
