Since the mid-'80s, northern Quebec's Voivod have forged a unique and globally influential sonic identity. Their shifting personnel has never tempered their iconoclastic yet ever-evolving sound, which juxtaposes death and thrash metal with dissonant prog and hard rock, fueled by jazzy riffs, odd and quickly shifting time signatures, home-made sound effects, and manic, thundering drums. Their lyric themes are inspired by dystopian and sci-fi imagery, political critique, and keen societal observation.
