Compiled using a single synthesizer, basic effects, and one take recordings, Black Unicorn's 18047 (the serial number of the Moog MG-1 used on the album) is an exploration of minimalist immersion. Following several recordings utilizing multiple synthesizers and multitrack recording, 18047 was created in preparation for a series of performances in the Pacific Northwest and the overall aesthetic comes from the requirement of fitting an entire setup into a single suitcase. The first side opens with a pulsing drone that grows to nebulae stutter and continues with submarine melodies and monolith synthscapes before moving to a thunderous growl and culmination in repeating notes and soaring melody. Side two washes up on the shore of some dark sea, where spectral sounds merge into galactic beeps, gigantic bowings, and robot lullabies that swell into oblivion before phased patterns and ethereal leads fade out.

The fifth release on the RCN Infinity Series, an imprint of Rubber City Noise focused on hand duplicated albums. Presented in a limited edition of 36 hand dubbed cassettes with printed j-card.
