Functioning more like a high school stoner’s science project than a proper band, Rainbows yield positive results with their third and latest electro freak­-pop EP Let’s Kiss. While sonically unorthodox, the methodology behind the songs is equally as rule­ defying. The Northwest-based artists Paul Walsh (Degenerate Art Ensemble, founder of ExEx Audio) and Max Stein (Wild Ones) steers clear from traditional rules of music production and writing, resolving the mantra behind recorded material to be defined without guitars, without organic vocals and be 100% improvisational. Both impressive on guitar, Walsh and Stein traded in their usual instruments for synthesizers (custom built by Wash) and replaced traditional composition for spontaneity.

And for two classically trained musicians, that’s some serious unearthing. While all three tracks seem to highlight the inventive, quirkier nature of the project – the quantifiable “banger” of the EP is “Bhangara College,” a track that sounds like the protagonists from Adventure Time decided to start a Black Moth Super Rainbow cover band but got lost along the way. The latter track, “Knuckles,” takes us down the rabbit hole to a heavier, more exploratory form of electronica, whereas the final track “Chords,” is a dreamy, spacious homage to earlier computerized soundscapes. While Let’s Kiss is improvisational in nature, paradoxically the EP is Rainbows most acoustically developed and catchy set of weirdo­-jam sessions to date. The duo thrives on the impromptu nature of the project and sense of discovery, and each release a more harmonic exploration of the electronic genre as a whole. If musical curiosity is similar to scientific curiosity, Rainbows just won the science fair.

Only 100 copies of the EP were printed, so pick up Let’s Kiss on hot pink cassette before the physical release disappears into the void.
