Yeah, I try to weed out the self-promotion stuff. If I see the same post in a few forums, I'll delete it. Anyone that specifically comes here to tell us about their band is generally ok, though, because they obviously feel that they'll appeal to fans of Ink and Tower, so it should at least have some potential.
Plus I like getting updates from Behold... the Arctopus and Actual Time because otherwise I'd never know when they put out new stuff
As for Sleep Terror, there were moments of brilliance, but overall I got bored. Too many blast beats, or whatever they're called. I think they have potential, though.
As for Alarum, I enjoyed their debut and the 2002 promo was excellent. I have yet to hear their new one, though Mark (their guitarist) said he was sending me a copy months ago. Maybe he got sidetracked.
One of my favorite tech death bands was Illogicist. Their demos were incredible, but unfortunately, they genericized their sound on their debut, I'm guessing to get more label support. 'Tis a shame, I thought they had huge potential.
