Boomkat Product Review:
Outstanding xenharmonic deep listening gear here from Stockholm's Mattias Petersson, who uses his compositional training to develop a triangular harmonic process he's been working on for two decades. Properly prismatic biz for anyone into Kali Malone or Éliane Radigue.
We won't pretend to know how it works exactly, but the foundation for Petersson's sickly drones is described as a "magic number triangle". The Swedish composer also known as Codespira1 was originally trained as a pianist, and is currently a professor of electro-acoustic composition at Stockholm's Royal College of Music, so you know he's serious about his craft. At this stage his interest in the triangle has been an obsession for 20 years, and he developed "Triangular Progressions" over this time using additive synthesis within a SuperCollider environment. Honestly to our ears it sounds shockingly meticulous, like a beautiful sculpture that's been unveiled after years of painstaking work. Petersson's organ-esque drones are disquieting at first, but as soon as the brain gets used to the unusual tuning, it takes on a magickal, almost historical quality.
There are clear parallels between Petersson's music and Kali Malone's studied, liturgical organ drones, but Petersson is more fascinated with unsettling harmonies and unexpected timbres. At an aesthetic level, it's very much computer music, but look deeper into the composer's obsession and there's a link to ancient forms of music that were often pre-occupied with hidden knowledge, sacred communication, and the frequencies of the natural world. Petersson's studied theories are one thing, but you don't need to have an academic qualification to feel the ineffable affect of these careful harmonies and melodies. If you're to accept the spiritual power of church music - particularly organ music - then it makes sense that it developed from something even more preternatural. By examining mathematical logic, Petersson reaches for the improbable, and unveils the inexplicable. Huge recommendation.
