La Puerta de Ariel is an 8-channel multitrack electroacoustic work. It seeks to penetrate certain auditory scenes that are presented to us from time to time. Here, there is a sonic territory where broad timbral layers develop within a fine line between everyday and distant sounds, that is, simple acoustic materials developed in a single space. The original sound materials used were obtained from the main door of my friend Ariel Gato's recording studio.
