Martin Tétreault, an internationally renowned Montréal DJ and improviser, was originally involved in the visual arts. His career includes various productions on compact disc and live performances with a range of collaborators such as Diane Labrosse, René Lussier, Jean Derome, Michel F. Côté, I8U, Otomo Yoshihide, Kevin Drumm, Xavier Charles, Ikue Mori and many more. Abandoning the musical citation he had used in his work when he began in 1985, he is now exploring the intrinsic qualities of the turntable: the sound of the motor, interference, and so on. He also uses needles, prepared surfaces (thanks to John Cage), and small electronic instruments. While remaining analogical, he has used the bruitiste approach, which has allowed him to leave aside the question of royalties and get himself invited to electronic-music events! When he feels the need for a break from music, he goes back to the visual arts, where he sands, scrapes, cuts up books and magazines, and so on.
