Sonde is a group of Montreal electroacoustic composers and performers. Their compositions were generally conceived for live performance on original sound sculptures. Through meditative improvisation, the group’s aim was to produce new music with sounds revealed by electroacoustic amplification and transformation.

Very active from 1976 to 1986, the members of the group included Andrew Culver, Charles de Mestral, Pierre Dostie, Chris Howard, Robin Minard, Michael O’Neill and Linda Pavelka. Since the beginning, Keith Daniel provided Sonde’s technical support.

This CD is the second release ever of Sonde, the previous one being Sonde en concert edited in 1978 by Music Gallery Editions. This CD is thus quite important, bringing to light part of the group’s archives. Optimized with today’s sound tools, all these recordings deal with waves of different kinds, sound waves of course but also organic and brain waves.
