MÜTTERLEIN is the solo project of Marion Leclercq (ex-OVERMARS), composer, multi-instrumentalist and vocalist.

Adopted in 2014, this pseudonym is a nod to the nightmarish yet fragile work of NICO, who in many ways deconstructed the unbearable myth of 'femininity' imposed on us.

Musically, MÜTTERLEIN mixes Post-Punk savagery, Doom, Noise, Industrial and Black Metal to create a vast universe of Post-Metal experimentation.

First album, "Orphans Of The Black Sun" – released in 2016 on Sundust Records, a label co-run by Vindsval from BLUT AUS NORD – leaned towards the Post-Punk and Doom registers using minimalist, cold instrumentation to create a record organic and ritualistic as a witch-dance around a fire.

In 2020, MÜTTERLEIN responded to an invitation by the artist LIMBES (ex-BLURR THROWER) to create a mirror piece to his epic 25 minute track entitled "Vérité" (French for Truth) for a split release issued in 2021 by LADLO. The free format allowed MÜTTERLEIN to experiment even further, constructing a slow, desolate dreamscape of doom-laden Dark Ambient.

"Bring Down The Flags", MÜTTERLEIN's second album, was released in late 2021 by Debemur Morti Productions. Dark, haunting and immediate, the album incorporated more electronic sounds and blackened Industrial atmospheres to serve a more direct subject and voice.

After a couple of years performing both solo and alongside TREHA SEKTORI following the release of "Bring Down The Flags", Marion helped forge a new entity, EITRIN, in collaboration with Dehn Sora (THROANE, TREHA SEKTORI) and Vindsval (BLUT AUS NORD). The alliance was conceived to commemorate the 20th anniversary of Debemur Morti Productions, with an instinctive and impassioned self-titled debut album released in December 2023. As a crowning moment, both MÜTTERLEIN and EITRIN graced the stage at the label's own Servants of Chaos festival in October 2024.

In early 2025, MÜTTERLEIN unveiled plans for a third album, "Amidst the Flames, May Our Organs Resound", a work that delves into the profound scars left by oppression throughout history. Anchored by an abrasive and darkly cinematic industrial soundscape, "Amidst the Flames…" is set to be released on May 9th.
