Hidden in Eternity is the Funeral Doom Death project of Néréïde, previous drummer of Stille Volk and current guitar player of Pantheist.
The "À Tout Jamais" album, where Kostas (Pantheist's leader) played the keyboard, is the second album of the band and marks a more frank turn towards a Funeral Doom Death punctuated with rhythmic breaks. Composed of four long songs, an instrumental interlude and a minimalist outro, "À Tout Jamais" plays on contrasts by alternating slow saturated passages "a la Ophis" and others more stripped and atmospheric.
