Sonoro is a series showcasing Mexican contemporary sound and radio artists. The pieces featured here are albums, collages and multivoice essays that lean towards analogous logics of sound capturing, slow listening, interspecies dialoguing and sonorous contemplation. Curated by Ana Martínez de Buen, these works present almost two decades of soundscapes and sound productions that offer a small sonic window into Mexican radio and sound art. Cordiox is a sonorous instrument made from fused quartz glass, taut strings and wood. It explores the reorganisation of signals from chaotic or entropic, thermal and electromagnetic sources using the principles of harmonic resonance. It is a large-scale mechanism that is proposed as an essay on the reversibility of chaos. Recorded at the church of San Lorenzo, 55th Venice Biennale, June 2013.Instrument design - Ariel Guzik; curatorial project - Itala Schmelz; sound production and sound engineering - Alejandro Colinas y Emilio Gálvez y Fuentes; executive producers - Catalina Juárez Oechler; texts - Karla Jasso and Ariel Guzik; translation - Teresa Carter; technical and electronic production - Leobardo Ramírez; graphic and editorial design - Maru Calva; photographs- Emanuele Basso, Marcela Chao, Laboratorio de Investigación en Resonancia y Expresión de la Naturaleza.
