"Much heavier than its predecessor, "A Perfect Forever" nevertheless retains the appeal to melody that very much defines Anubis Gate. The compositions on this album are more complex than those on "Purification", and they contain numerous changes of time and tempo. Fans of progressive metal along the lines of Fatew Warning and Queensrÿche should like this album as should fans of classic metal along the lines of Judas Priest, Mercyful Fate and King Diamond."
