Ryoji Ikeda

An alphabet reduced to its bones. Twenty-six words, twenty-six frequencies, twenty-six grooves that never end. Code Name: A-Z is Ryoji Ikeda at his most austere and his most physical, a record that treats the vinyl disc not as a carrier of music but as an instrument in its own right. Ikeda's position in the landscape of experimental sound needs little rehearsal. A founding presence in the Kyoto collective Dumb Type and one of the defining voices of Raster-Noton across +/-, 0°C and Matrix, he spent the late 1990s and 2000s stripping electronic music down to sine tones, clicks and the thresholds of human perception. Where his peers explored texture, Ikeda explored data: the datamatics and test pattern series translated raw information into strobing black-and-white fields and barcode rhythms, works that have since filled museums from the Centre Pompidou to the Park Avenue Armory. Code Name: A-Z comes from that lineage. It was first issued in 2017 by The Vinyl Factory for Elevation 1049, the arts festival in Gstaad produced by the LUMA Foundation, where Ikeda presented a site-specific installation of test pattern against the Swiss Alps.

The premise is a single chain of translations. Each of the 26 words of the military spelling alphabet - Alfa, Bravo, Charlie, through to X-Ray, Yankee, Zulu - is converted into Morse code. The dots and dashes are then sonified with a set of chosen frequencies, compressed into a loop of 1.8 seconds, and cut as a locked groove: thirteen per side, each title hand etched into the surface of the clear vinyl. Drop the needle anywhere and one letter repeats indefinitely, a pulse of pure tone stuttering in its own orbit until the arm is lifted. Move it a few millimetres and the language changes.

What emerges is less a listening experience than an environment. The frequencies sit high and dry, closer to the sound of test equipment than to synthesis, and the locked groove strips them of development entirely. There is no arc, no build, only the insistence of a signal that was designed to carry meaning across noise and now carries nothing but itself. The Morse rhythms, once vital to naval and aviation communication, become skeletal percussion. Played at length, the record starts to behave like one of Ikeda's installations: the room fills with a single held pattern, and attention drifts from the sound to the space it occupies.

There is a quiet lineage here that runs back through Christian Marclay's manipulated records and Milan Knížák's Destroyed Music, artists who understood the groove as sculptural material. Ikeda's contribution is to bring to that tradition the rigour of the code itself, turning a communications protocol into a set of minimal compositions that exist only in the act of playback. It also sits alongside the label's other Ikeda editions, from the supercodex series to the recent data-cosm [n°1], as part of a sustained engagement between artist and pressing plant.

The original 2017 edition disappeared quickly and has been difficult to find since. This repress, mastered by Noel Summerville at 3345 and housed in white Perfect Image outer and inner sleeves, is limited to 500 copies worldwide. A conceptual object as much as a record, and one of the clearest statements of what Ikeda's work is about: the point at which information becomes sound, and sound becomes matter.
