I get quite a melancholy vibe from the first three albums. I guess that has to do with Mattias vocals to an extent (Portal of Light, Grave of Guilt etc), but is also true on tracks such as Night of Infamy and of course Hear Me Pray (OOOH, wait with paradise....hell yeah!). The new album puts me in mind of a more "f*** you" mood on many songs (I mean that in a positive way :P ).
