This is what I love about Opeth.... It's not just the music, but the feeling and the atmosphere.... people can have whole threads discussing the atmosphere alone.... As for Deliverance, maybe there aren't any forest moments (I don't feel it in MAYH or SL either) but it does have its share of eerie moments.... the carnival is so awesome, as is the backward voices after the silence.... I think the best atmosphere comes from BWP.... swamps, forests, autumn.... you name it... BWP is amazing in the way it can conjure up such images and atmosphere. It's more than just music to me....
