The intriguingly titled “Deep Thought Glacial River” refers to a recurring dream Caleb experienced prior to writing the tracks: “... the dream was about an expedition that leads into a glacier, inside there's a whole river cave system that eventually leads to an ancient ice metropolis deep inside of the glacier”. Within the frame of Caleb’s dream the near 44 minute piece serves as a concept album to tell this story.

Drawing on broad musical influences from post-noise Casio based recordings, progressive rock and classical Indian music; Dravier creates a tapestry of sounds, utilizing vignette-like song structure to stitch together otherwise incongruous, separate recordings. The almost psychedelic euphoria of opening track “Journey Towards Mouth of the Erebus” being a brilliant case in point. A2, “Discovery (the Ancient Ice Cave River System) and B1, “Past Frozen Whirlpools and the Dark Zone Mind” take the listener deep into the glacial labyrinth; the drones and swells reflecting the awe and grandeur of this frozen sub-aquatic maze. The trepidation of the onwards journey is captured perfectly in the increasing sense of introspection and expectation. B2, “Suite for a Lost Glacial Metropolis”, sees the intrepid traveler emerge from the subterranean river basin and enter the majestic lost metropolis. This final piece courses with optimism and amazement; a gentle kick drum underpins heavenly, celestial synths before dreamlike looped guitars and barely audible percussive rhythms confirm that, finally, we have arrived.
