Canadian electroacoustic composer Francis Dhomont offers a 50 minute cycle of pieces paying tribute to musique concrète pioneer Pierre Schaeffer. Describing the opening piece as a “funeral march”, Dhomont shapes a paraphrase out of material from the latter’s Étude aux objects. AvatArsSon draws a trajectory between Schaeffer and those composers he has influenced, including Xenakis, Stockhausen, Berio and Luc Ferrari. The third piece suggests a connection between Schaeffer and the 14th century French composer Guillaume de Machaut. This being a cycle, the final section, Phonurgie, draws all the various strands together. Dhomont’s piece is superbly crafted and does everything an electroacoustic composition should, but is that really enough?
