ERYN NON DAE. formed in 2001 under the name END. and worked on their musical expression until early 2004.

At the beginning of 2005, ERYN NON DAE. entered ConKrete Studio with Mobo in Bordeaux to record the EP, The Never Ending Whirl Of Confusion.

Critics then were unanimous in their high regard for the musical quality of the band. The music is aided by the fact that ERYN NON DAE.’s live show is as aurally oppressive as being crushed by a steamroller. This presence was crucial in spreading their name via live performances with the likes of Gojira, JenX, Sybreed, Black Bomb A, Pelican, Sleepers and High On Fire, among others.

Before even going to the studio to record their first album, ERYN NON DAE. took part in Hellfest in 2007.

Next on the band’s slate was the writing and recording of Hydra Lernaia. The album was also recorded, mixed and mastered by Mobo at ConKrete Studio in Bordeaux, France.

As per its mythological definition – the mythical nine-headed serpent, slain by Hercules, that grew two heads in place of each one that was cut off, unless the wound was cauterized – Hydra Lernaia explores nine human feelings as many-sided problems that present new difficulties each time one aspect of them seems to be solved or overcome. Each song is a feeling; each feeling is an incurable disease that tortures the heart of man.

With a worldwide release through MetalBlade records in 2009 the band changes his name from END. to ERYN NON DAE. The band increases his audience and starts playing across Europe and festivals with bands like The Ocean, Kruger, Hacride and others...

Writing process for Hydra Lernaïa’s successor began quickly in 2010, the band wants to go further with ambiances dynamics and contrasts. Meliora’s recording took place one more time with Mobo from the Conkrete Studio, trying to render this new direction through a long and demanding recording process.

Meliora is released in 2012 and allows the band to go back to the road in France, Germany, Spain, Swiss and Italy, with Gorguts, friends from Gorod or Nero Di Marte and to headline their first UK tour. They played SWR festival in Portugal, Euroblast in Germany and they go back to Hellfest in 2013.

The band is already thinking about a new record but the will not to repeat themselves is slowing down the writing process. 2014 and most of 2015 are spending with only few gigs, discussions and few rehearsals.

As the writing process always started with Yann and Franck guitar riffs, a different process starts this time and songs begin to pop up as the band is writing around a more limited collective based on Mickaël and Julien, guitars become more textured and noisy, electronics appears and Mathieu try to explore some new directions with vocals, while lyrics are getting more universal. These textured new songs are opening new doors and the band calls long time collaborator Mobo again to handle the recording in august 2017.

Abandon Of The Self came out in 2018 through Debemur Morti Production.

« Since forming in 2001, gifted French band ERYN NON DAE. have created a uniquely claustrophobic universe and this stellar fourth opus is a monumental wave of melancholy and despair - a fascinating combination of post-apocalyptic fury and vast ambient passages.

The most amazing thing about Abandon Of The Self is the exceptional ease with which ERYN NON DAE. place an inventive, water-tight rhythm-section at the heart of staggeringly complex songwriting. Their music is beautifully structured, driven by extraordinary guitar manipulations and an intense, wide-ranging vocal performance. » According to the press release.

The band went back to the road and played a few gigs during a year including Toxoplasmose Festival in switzerland before Franck moved to Chile.

The writing process of Abandon Of The Self’ successor started around 2018 and the decision is taken to write songs with just one guitar, trying to find a new way to use it compared to what the band did from the beginning and their usual multi layered guitar work. The band wanted to dig further that textured direction Abandon Of The Self opened and Julien, Mickaël and Yann start to work on new ideas. Trying to melt the guitar into the electronics, focusing on one strong idea per song instead of having too many riffs. Most of all, Mathieu wanted his vocals to evolve, trying to achieve more honesty and to capture moments of expressivity rather than the perfect take.

The band worked on new songs until the covid appears. This moment left its mark upon the band operation and most of all on Mathieu’s relationship to creation within the band. Through this very long process, new path have been discovered, writing music for ERYN NON DAE. never felt so strange. Many new ideas are twisted during months. Working sessions are rare but intense, Mathieu’s vocal style is slowly evolving according to his emotional state during these sessions. The band worked on eight new songs.

In June 2023, Mathieu died.

Through this unspeakable ordeal, the decision was made to finish that record. The band always recorded a lot of demos, Mathieu’s take were solid enough to decide to use them on the record, as an hommage, as the only possible way to put an end to this more than twenty years chapter of Franck, Yann, Julien and Mickaël’s lives.

This record is Called Disunited States Of Anima, as Mathieu named it around 2022. This very special album is released by the band themselves in 2025. The very limited run of the physical version has been entirely handcrafted, patiently thought and conceived during long months.

Disunited States Of Anima stands as ERYN NON DAE. emotional testimony to what these 25 years of creation has been for Mathieu, Julien, Franck, Yann et Mickaël.
