Ok, I've listened to a few of Liturgy's tracks now so I feel I can contribute to this, as a man currently handling the vocals of a black metal band (ok, prog. black metal but whatevs). Fuck this band. They are competent musicians but their songcraft is boring as hell. The vocals are almost comical, sure they're pretty good screeches but I don't feel any kind of emotion behind them and I've always thought black metal was supposed to be emotive as fuck. The whole thing just sounds...impotent. All I hear (and granted this is coloured by reading this thread and the dude's writing before hearing any of their music) is boring music played by boring people, completely without feeling or emotional investment in what they're doing.
Fuck. This. Band.
