I also listened some tracks from "Seer Of Decay" by Grunt yesterday while paying a visit to my father who has quite supreme sound system and I can honestly say, the album sounded phenomenal. I have quite acceptable sound system as well but not nearly as good as my fathers and my space is quite limited so I can't really place the speakers properly. Anyway, the album opened up in completely different way. Sound was big, clear and crunchy. I was able to point out every little detail from the tracks and it left me completely mesmerized. It even amazed my jazz-freak father (before he left the room, holding his ears, haha).
Most of the releases leave me graving for more but "Seer Of Decay" leaves me completely exhausted. Like I would've been with Mikko, banging some metal for the whole day and then sit down to a couch with him and listen to the final results (haha, sorry).
