Not everyone on this board will excuse your ignorance, but to answer your question, not only are they still around, but they are about to kick ass with "We've Come For You All" (to be released April 1, 2003 in North America).
You can be excused for not hearing their last studio album, Volume 8:The Threat is Real, as the label went bankrupt shortly after it's release in 1998. If you can get your hands on a copy, it's worth it, as it's one of the best recordings to come out in the 90's. Since that time, they have been busy, but secondary to 9/11 and all sorts of crap with getting a new label, the newest album has been delayed for over a year.
