Dekmantel regular Matrixxman returns with the third, and final instalment in the Sector series, Part III: Polyphony. In this triptych, the producer from San Fransisco sets out to highlight the key components behind the sounds and style of techno, exploring the range within the confines of a particular limitation. Following Parts I and II, which looked at Rhythm, and Acid, Charles McCloud Duff charters the realm of Polyphony with four, meticulously produced techno tracks, expanding his repertoire of cult, dancefloor music. . Polyphony refers to the simultaneous combining of many notes in a musical sequence. In electronic music, this specifically refers to the role of the synthesiser - such as the Minimoog, ARP Odyssey, which can produce different pitches simultaneously. Polyphony has been an integral characteristic of the genre’s sound for over a quarter of a century, and can be heard in many key records, living a the sonic forefront of these four tracks. ”Sector Series: III Polyphony” provides an exercise in melody and polyphony. Throughout the EP, swaggering rhythms are inter-washed with a sea of multi-melodious, reverberated notation. ‘Initiation’ resonates with the grandiosity, and harsh claustrophobia of early Underground Resistance. ‘Access Granted’, drives hard with pulsing effects, with a dystopic, rhythmic cacophony of euphony. ‘Desert Planet’ plays around with a differing tempo, imagining a more fantastical vision of music, echoing back to earlier Plastikman productions, using a vast sonic spectrum to conjure up a colour palette of alien imagery. ‘Horizon’ rounds things off; a track that builds on minimalism with a progressive composition, allowing the polyphonics to drive the track, harnessing the adept production qualities that Matrixxman has come to be recognised for.
