Analysis of information sources in references of the Wikipedia article "Into the Pandemonium" in English language version.

Released in 1987, Into the Pandemonium would substantiate these claims and then some, introducing an unconventional collision of death metal brutality and symphonic overtones on its way to becoming one of the classic extreme metal albums of all time.
