"Eric Normand is an improviser, bassist, instrument designer, composer, songwriter, singer and record and concert producer. He defines himself as an epidisciplinary musician, a free electron driven by its yearning for meetings. As an improviser, he develop a personal and radical playing on a homemade electric bass equipped with mics and objects feedbacking and vibrating in small electronic devices, creating electric flux interrupted by the instrumental gesture. With this set, he prefer to play duets, with Jim Denley (flute and sax), Philippe Lauzier (bass clarinet and sax), Sébastien Cirotteau (trumpet), Pierre-Yves Martel (viola de gamba and electronic), Jean-Luc Guionnet (saxophone), in addition of several spontaneous encounters.

He also play in bands involved in a more specific musical genre as danced poetry with BABABA, instrumental theatre with Le Veau/ The Veal, songs with Les Pitounes and Éric Normand Chante and folk music with The Surruralits and RRRRoyal Canadian Free Form Folk Experience. Interested in collective creation and orchestral improvisation, he lead for seven years the GGRIL, a 15 pieces band that have worked with composers such as Evan Parker, Jean Derome, Robert Marcel Lepage and Michael Fischer. His music has been programmed by or performed in several festivals in Canada , Australia and Europe. It have also been broadcasted by Radio-Canada, Australian Broadcasting Corporation, CBC, Radio-Grenouille, and several college radio stations."
