I don't understand what you are talking about. Orchid was just totally unpolished and tried to meld the quiet bits with the loud death metal bits. Morningrise polished that sound and had some great interludes. My Arms, You Hearse was totally brutal and is their second heaviest album by far. It also had a different feel to it than the past releases. Still Life was different in that they started to go away from their death metal roots and become more progressive and they started to add more jazz elements. Blackwater Park is a polished version of that album and it is a bit more heavier. Then you have Damnation, which is obviously different than the other releases and Deliverence, which is heavier than anything they released and took away the whole folk/jazz feel of the other albums. The band tried to be as brutal as possible with that album. Ghost Reveries is probably their darkest album, most likely because of the keyboarRAB used. It was definitely influenced by the funeral doom metal scene. Now what was all this talk about them not progressing?
