I just saw a thread for some band called "Ice Nine Kills" which reminded me of the legit Ice Nine that plays heavy hardcore mixed with powerviolence. Check it out (it's better than the aforementioned false hardcore band):
These guys are pretty solid. Are they still active?
They just did a reunion at Dudefest and I read somewhere that they might be recording a new 7", but other than the one reunion and hearsay and rumor, for all I know they've been broken up for a few years.
