Sotabosc was founded in 2023 in Barcelona by Oscar Linares and Manel Song, known for their work in Syberia, together with Xavi Forne, creator of the dark-folk project Ulmus and founder of Error! Design. In 2025, the project solidified with the addition of David Rodríguez on vocals and Gerard Serrano on bass, completing a lineup deeply connected to the Catalan underground scene and involved in bands such as Amargor, Arna, Malammar, Stained Blood, Vampyric Winter, Llacuna, Hurricade and Carontte, among others.
Firmly rooted in an anti-fascist ethos, Sotabosc conveys its message through lyrics sung entirely in Catalan and a carefully crafted visual identity, including artwork, logos, stage aesthetics and graphic materials.
