I've only heard Wormphlegm's demo. Everyone seems to have the LP, but no one wants to talk about it, for some reason. Every time I ask someone, they just say that it's 'really sick and awesome' and refuse to elaborate.
Anyway, I *believe* that they're moving away from the dark ambient and drone infused style that they did before to just do straight, very extreme doom/death. A video clip of them playing one of the new songs can be found here: http://www.stillonline.be/. Enter, go to the One Camera Video section, go to W, and go to Wormphlegm. Tell me what you think.
Anyway, can you elaborate on why you disliked the demo so much? I found it very good.
