The concert that gave birth to the Parasites duo, with Diane Labrosse and Martin Tétreault. Music made from records, sampled sounds and sound recycling. Improvisation and creation, but also composition, a form of composition invented for vari-speed turntables, Conceptual, contextual composition drawing its resources from trafficking and taking into account the fragile nature of vinyl; generations of snaps, crackles and pops. Composition requiring constant focus and invention from the sound recycler.
