I think Impious is an excellent band. The latest album didn't do much for me although I might need to give it more listens as music sometimes grows on me, and it does have potential. Check out Hellucinate for a kickass album. Nice vocals too.
Edit : Holy shit they have ANOTHER album out? Awesome. I was unaware of this new release so nevermind my above comment. So far this myspace song is kickass
Pierced is definitely better than Effigy since Effigy kinda fades after the first four songs + Effigy is just full on brutality. Pierced has brains along with the balls
