I have two Arch Enemy albums. They are really heavy with female growl vocals by the superb Angela Gossow. Angela has decided to move into the band's management instead of being on the frontline. The new vocalist will be Alissa White-Gluz, who is herself awesome, from the band The Agonist. The Agonist have replaced Alissa with Vicky Psarakis. I haven't got any albums by The Agonist but I have seen videos from both and they are awesome songs. The Arch Enemy and The Agonist new albums are going to be awesome.
