Just listened to that new track... I can safely say it's the first Arch Enemy song I've listened to in about ten years. The music sounds like standard melo-death, the vocalist sounds alright. I do remember Gossow sounding particularly venomous though. Anyway, I didn't think the new singer sounded flat, and she fit the music. Unrelated: as a politically incorrect male who enjoys looking at beautiful women, Alissa White-Gluz fits the bill.
I love inside jokes, I'd love to be a part of one some day.
