The conception of Sinsaenum can be traced as far back as 1998, when
Frédéric Leclercq (best known as the longest-serving bassist of English
power metal band
DragonForce) began writing a number of
death metal songs. After recruiting fellow guitarist Stéphane Buriez of
Loudblast for the project, Leclercq was contacted by drummer
Joey Jordison (known for his work with
Slipknot, then a member of
Murderdolls,
Scar the Martyr and later of
VIMIC) with the intention of working together, who later became involved in the project. Jordison proposed the band name Sinsaenum, a modified
portmanteau of the words "sin" and "insane". After a music video for the song "Splendor and Agony", the band's debut full-length album
Echoes of the Tortured was released by
earMUSIC on 29 July 2016. In early 2017, the band entered the studio again to begin the process of writing and recording what they dubbed as "Sinsaenum II". It was later announced in summer that year that the band would release a new EP. The EP, entitled
Ashes, was scheduled for release on 10 November, featuring new music, previously Japan exclusive bonus tracks, and an alternate mix of the track "Dead Souls" from
Echoes of the Tortured, remixed by Frédéric Duquesne of French
nu metal group
Mass Hysteria. The title track was released with a music video on 29 September 2017. On 27 October, they released the Duquesne mix of "Dead Souls" with a lyric video. Their second album,
Repulsion for Humanity, recorded in Sainte-Marthe studio in Paris by Francis Caste, was released in 2018, followed by a European tour. The album differed from the previous work by the presence of
groove- and
nu metal sound. On May 21, 2025, the band revealed that their third album,
In Devastation, would be released on August 8. They also released the title track to the album and announced former
Breed 77 drummer André Joyzi as the replacement for Joey Jordison. == Band members ==
