Pierre Berthet

A performance for reversed "filter Queen" vacuum cleaners (They don't suck, they blow.)

A flexible tube is attached to the end of an inverted (hence blowing air) vacuum cleaner. Because of the force of the air stream, the tube starts frantically swiping the floor in a swift regular pendulum-like movement, and thus the air swooshes along the openings of a number of rigid tubes of varying lengths that are fixed on the floor in its path. The result is a mechanical sort of ’air drumming’ superposed on the vacuum cleaners’ continuous low buzzing motor drone.

Pierre Berthet lives and works in Liège, Belgium. Musician, composer, inventor, craftsman. He studied percussion with André Van Belle and Georges-Elie Octors. Improvisation with Garrett List. Composition with Frederic Rzewski. Music theory with Henri Pousseur. He designs and builds sound objects and installations (steel, plastic, water, magnetic fields, ...). He presents them in exhibitions and solo or duo performances. He worked with Frédéric Le Junter, Pierre Bastien, dj Low, Rudi Trouvé, and played percussion with Arnold Dreyblatt ("Animal Magnetism" on Tzadik, "The Sound of One String" on Table of the Elements).
