P'derrigerreo is a project by G Patrick Foley and Pierre Plantevin, who live in the United States. Although they look mysterious because they have released few works, they create very interesting sound collages with their unique sense. This work has the texture of a collage that seems to have been made using tape manipulation, and it reminds us the some eerie works of Nurse With Wound while changing their style from sound collage to noise acoustic, the precision of the electroacoustic compositions or musique concrète works pursued by Pierre Henry, etc, and the intuitive improvisations made by operating a cassette tape player. However, these different approaches do not just seem to be mixed together in a disjointed way, but are created with a strong cohesion. This work is full of outstanding sense and technique.
