I think more bands should not have vocalists like Animals As Leaders, etc. So many times I hear a band that I would like except for some sissy ass singer. Even some bands are influenced, and will play some shitty melodic whiny bitch interlude, so the singer can express his emotions (fear factory, faceless, periphery, devil wears prada, etc.). It's really bad in "death core"... and actually some of those riffs and breakdowns are pretty bitchin, if it weren't for the black-haired emo cutter with tight jeans and a flap of hair covering one eye crying and why god'in all over the stage.
Speaking of bands without a vocalist... was surprised/impressed to hear this Cacophony cover on my playlist the other day.
