The “GML Variations” album started with a commission to compose a piece for the Robotic Gamelan of Casa da Música, in Porto, to be presented with other works in a public showing spanning several days. “GML 123” was a generative system that controlled the actuators in the Robotic Gamelan while projecting several other sounds into the very resonant space of Casa da Música’s foyer. The piece was presented in January 2018 and shortly afterwards recorded in the same location. After receiving the recording, we found ourselves being drawn to it over and over and, as often happens to us, we started experimenting: revisiting the original composition, manipulating its recordings and creating new material, eventually developing the four variations and coda that complete this album.
Pedro Tudela and Miguel Carvalhais collaborate as @c since 2000, composing, performing, and creating sound installations. They have released and performed extensively, often collaborating with other artists and collectives in a practice marked by radical experimentalism with computational sound. In 2003 they established Crónica, a label dedicated to experimental music and sound art, that they have run since.
