Back in ‘88, with their 4th LP “Dimension Hatross”, Voivod usurped Celtic Frost’s throne as THE pioneers in avant-garde heavy metal. But “Killing Technology” came close to doing it a year earlier against Frost’s “Into the Pandemonium”.This album has all of the aggression of their earlier works, and the technical proficiency of later releases. With more intricate guitar-work and intense percussion than you will hear in music with this much raw energy. If you’re interested in which albums have had the most impact on metal; this is a must.
