I don't believe Kurlzz is the actual one Screaming on Undead/Among other songs. Shouting, yes. But Screaming? No. If we have all these screams as Kurlzz and have The exact same sounding scream on Pain ("Goodbye!") as Deuce, why isn't he the screamer for all those screams on Swan Songs? Not changing the vocalists until I get statements on this.
