CEPHEIDAE VARIABLE Shares New Guitar Playthrough “Zephyr of Ouroboros”

Progressive metal solo project Cepheidae Variable has released a striking new guitar playthrough video for “Zephyr of Ouroboros”, a centerpiece track from the debut album "Primordial Reverie". The video showcases the intricate musicianship and layered storytelling that define the project, offering fans a closer look at the technical and emotional depth behind the music.

Formed by guitarist and composer Ryan Koepke, Cepheidae Variable began as a personal exploration of musical growth, but quickly evolved into a fully realized artistic vision following his father’s cancer diagnosis. The project became both a creative outlet and a deeply personal journey, reflecting life’s turbulence and resilience.

​"Primordial Reverie" is a concept album built entirely through instrumentation, weaving orchestral elements, synths, and guitars into three distinct acts. “Zephyr of Ouroboros” marks the conclusion of the album’s first act, opening with a windy soundscape and orchestral arrangement before diving into odd time signatures, soaring violin‑guitar harmonies, and circular song structures that mirror the eternal cycle of the Ouroboros.

Koepke describes his writing process as “like writing a book,” with each track supporting the next to create a cohesive narrative. The playthrough highlights his ability to fuse technical precision with emotional storytelling, drawing influence from bands such as Dream Theater, Haken, Intervals, Wintersun, and Caligula’s Horse.

Released earlier this year, "Primordial Reverie" is available on all major streaming platforms and on CD. The album moves from symphonic fantasy atmospheres to sci‑fi‑infused progressive metal, balancing melody, chaos, and experimentation. With artwork by renowned collage artist Alex Eckman‑Lawn, the record invites listeners to craft their own imaginative journey through its evolving soundscapes.

​Cepheidae Variable plans to continue evolving, with future releases potentially expanding beyond instrumental compositions and even beyond the solo format. For now, the “Zephyr of Ouroboros” playthrough offers fans a glimpse into the heart of the project, a fusion of technical mastery, emotional honesty, and boundless creativity.
