They sound, however, like the bands I used to listen to when I had a skateboard: DRI (duh), Siege, Thulsa Doom. Fast, tight instrumental sections with a screeching vocalist who may or may not have hit puberty yet (Heresy, eatcher heart out). I basically divide bands in this genre into two groups: those who can actually pull off the stop-on-a-dime instrumental time changes, and those who can't. Congenital Death is in the former category, and it's a pretty good demo. I don't have a lyric sheet in front of me (left it at the office, go figure), but I think they're singing about, uh, politics and lifestyle choices.
Anyway, pretty good stuff, and worth a spin, which you can do here. Pick up the tape over at Ranch Records. Congenital Death is playing Smash it Dead Fest in March, so check it out if you're in the Boston area-from what I understand it's a benefit for the Boston Area Rape Crisis Center (BARCC).
