Ondes Martenot
"Wavemakers" includes a performance by musician Jonny Greenwood, filmed during a Radiohead soundcheck. Greenwood, who was self-taught on the instrument, stated after his performance Binet-Audet pointed out a technical error in his playing style. The film also features interviews with Jean-Loup Dierstein, an electronic-instrument repairman-turned-Ondes Martenot maker, who was commissioned by Greenwood to build him a new instrument, Binet-Audet, as well as Montreal-based Ondiste Jean Laurendeau.
