Metal Retardation is the first in a series. The interviews were transcribed into interviews for the director's metal magazine, "The Grimoire of Exalted Deeds." The interviewer asks bizarre questions, resulting in highly amusing reactions. Bands include King Diamond, Peter Steele, My Dying Bride, Turisas, Ensiferum, Nevermore, Cannibal Corpse, Arch Enemy, Impaled Nazarene, and Tyr.
