Emerging from British Columbia, Canada. Cepheidae Variable is a progressive metal project known for blending technical precision with cinematic atmosphere and narrative-driven composition. Founded by guitarist and composer Ryan Koepke, the project began as a vehicle for exploring complex rhythmic ideas, melodic lead work, and expansive sound design rooted in modern progressive metal. Early releases established Cepheidae Variable as a project focused not on virtuosity, but on mood, storytelling, and emotional contrast.

As the project evolved, Cepheidae Variable expanded beyond its original solo framework into a collaborative band entity, allowing the music to grow in scale and depth. Drawing influence from progressive and extreme metal pioneers such as Haken, Dream Theater, Opeth, Devin Townsend, and Between the Buried and Me, the band’s sound balances heavy, riff-driven passages with ambient textures, orchestral elements, and dynamic arrangements that reward repeated listening.

Cepheidae Variable has gained attention within the progressive metal community with its independently produced debut release, drawing listeners in through a balance of aggression, atmosphere, and detailed composition. The project’s meticulous production and compositional ambition reflect Ryan Koepke’s background as a producer and multi-instrumentalist, presenting a clear artistic vision and a strong commitment to sonic detail.

With new material currently in development, Cepheidae Variable continues to refine and expand its sound, positioning itself as a focused and evolving voice within modern progressive metal; one rooted in depth, intention, and immersive musical storytelling.
