[Repeated from Wednesday 11am.] A series showcasing Mexican contemporary sound and radio artists, curated by Ana Martínez de Buen. This week: Campo Blanco by Ariel Guzik. These recordings originate from a family of string instruments designed to explore various types of chaotic signals, considered as possible sources of sonic languages. The first of these instruments, the Plasmaht Mirror, comprising strings, wood and electromagnetic resonators, operates primarily using signals derived from living plants. Ariel has called the resulting progressive cascade of harmonic sounds a "harmonic field." Also featured here, the Harmonic Quartz Windows, were designed to elevate these experiments to a level of purity achievable by using fused quartz crystal membranes – rather than wood – as harmonic resonators. The signals employed here originate from thermal noise emitted by silicon crystals. This special edition of these works includes essays written by Ariel Guzik, voiced by Juan Stack, originally recorded for Radio UNAM, and curated for this broadcast by Ana Martínez de Buen.
