Instrumental Interaction II (2023)

Program notes

"Instrumental Interaction II explores the sonic and gestural relationships between the Karlax, a clarinet-like MIDI controller with an undefined identity, and the tenor saxophone, an agile, variegated and powerful instrument. A piece that focuses on the importance of gesture in musical interpretation but also on the kinetic evocation carried by the music itself around two communicating vessels/instruments.

Benjamin Lavastre is currently a PhD candidate at McGill University and a member of CIRMMT. The creation of his piece tonight is part of his ongoing doctoral research on this digital instrument.
