Primordial Reverie Debut Concept Album metal artist Cepheidae Variable

Entropic Harvester
Single · 07.22.2026

Comprised of members from British Columbia, Canada and Stockholm, Sweden, progressive act CEPHEIDAE VARIABLE has unveiled “Entropic Harvester”. This single release is the first offering to feature new vocalist Chad Bernatchez.

Accompanied with a lyric video, “Entropic Harvester” sees the the protagonist of the album’s narrative set foot on a new world only to discover remnants of life. What remains is “a biomechanical spider-like machine that has consumed everything on the planet. Not out of malice, but because it believes life to be wasted energy”, CEPHEIDAE VARIABLE explain. 

Upon encountering the ‘Entropic Harvester’, the protagonist must fight for her life. The ensuing battle leads to the destruction of the machine, allowing the space adventurer to explore this new plain freely.

“Entropic Harvester” is one of the band’s most technically demanding tracks. An eerie cinematic soundscape evokes the barren landscape of a consumed planet. Across the song, numerous time signature changes, the frequent development of the central motif, and multiple intricate guitar solos culminate into a complex yet fully immersive arrangement.

Primordial Reverie
Album · 11.07.2025

Primordial Reverie is a fully instrumental concept record built around evolving biomes and acts in the absence of lyrics, combining recurring motifs, layered orchestration, synth textures, and guitar-driven themes into a cohesive narrative arc.

Blending technical, riff-driven writing with melodic leads, odd time signatures, orchestral arrangements, and evocative soundscapes, the album focuses on atmosphere, emotional contrast, and cinematic progression.

A vocal reimagining of the album is currently in development, expanding upon the original material through new lyrical themes.

“Genuinely exciting.”
– Prog Magazine

“The harmony of sounds and atmosphere that emerge hit the mark perfectly, delivering moments of pure poetry: a blend of technique and inspiration pushed to decidedly high qualitative levels, confirming the compositional and interpretive skills of an artist of real substance.”
– Rock Hard Italy

“Without vocals, the artist has to work harder to convey his feelings and emotions in his music, and Ryan did that well. Many of the melodies you can hum or sing along with, and that’s a testament to the instrumental album.”
– Metal Temple

“It’s easy for instrumental metal, and for progressive metal, to lose their emotional punch in a pile of clever passages. Ryan Koepke does an excellent job maintaining poignancy throughout Primordial Reverie‘s hour-ish run time. This album does feel like a singular journey that takes the listener into different emotional headspaces as the music unfolds.”
– Metal Utopia

“The musicianship is undeniable, with Koepke proving himself a highly capable guitarist.”
– Metalized Magazine
