Kataklysm is a Canadian death metal band. They call their musical style "northern hyperblast" after an advertisement in M.E.A.T. magazine describing another band, Fear Factory, as "hyperblast". The term refers to the extremely fast blast beats that Kataklysm's former drummer, Max Duhamel, fused into the music. Kataklysm was formed in 1991. At the beginning of their career they were mostly known for being one of the fastest, most chaotic metal bands. Genres - Melodic death metal, death metal. Associated acts - Dechrist, Ex Deo.
