The debut album by Alcest, Souvenirs d'un autre monde, released in 2007, marked the beginning of the band’s extraordinary career. With the release of Souvenirs d'un autre monde, Alcest mastermind Neige forged a radiant new sound that balanced on the edge of metal while simultaneously conveying emotions of euphoria, bliss, and nostalgia. The singer and multi-instrumentalist dedicated the album to his childhood memories of experiences in a spiritual other world — personal themes that would later become conceptual cornerstones of future Alcest albums. Souvenirs... became known as one of the foundational releases of the blackgaze/post-black metal genre, a record that continues to influence countless other bands in its wake.
