The California-born, London-based producer Rrose is well known for taking dancefloor techno into the uncharted depths of experimentalism and psychedelia while also paying homage to artists of the 20th century avant-garde such as Marcel Duchamp, James Tenney, and Eliane Radigue. "Beware of Shells" (the first solo Rrose release of 2018) is a diverse five track EP that goes to extremes of both aggression and tranquility while remaining strangely cohesive. The EP opens with machine gun bass drums that slowly disintegrate into a swirl of undulating tones and ghostly resonances. Next comes "Incisors" - the most solidly dancefloor track of the EP - which establishes a primal, skeletal rhythmic base upon which snake-like analog synth lines interweave in unpredictable ways. "The Swelling" follows with a short, sparse study in feedback, bent into uneasy melodic patterns. Side B opens with a previously unreleased 2013 remix of the Los Angeles band Deathday, and is perhaps Rrose's most overtly "industrial" track to date, with buzzing, dissonant synth tones that sound somewhere between a foghorn and a distorted guitar. The EP finishes on a contemplative note with "Pecking Order," a microtonal, ritualistic affair conjuring the spirit of Wendy Carlos's little-known masterpiece "Beauty in the Beast."
