Copenhagen composer Niels Lyhne Løkkegaard's long form work refers to units of compositional structure in systems of instruments, each a "bubble" that interacts and collides creating fluctuations, ruptures and tension release in an hypnotic sonic tapestry, performed by Montreal's Quatuor Bozzini on violins, viola, cellos and harmonica; mesmerizing.

Using only their right arms and never fingering the strings with their left hand, this recording of Alvin Lucier's "One Arm Bandits" was recorded in Lucier's own dining room, the hour-long piece in four parts exploring the relationship between bow direction changes and shifts in phase, scored for four cellists and performed by Tyler J.

French electroacoustic composer and innovator Eliane Radigue's final work made with feedback material from 1970, five pieces that strip away at the familiar, deconstructing and decomposing classical works into mesmerizing drones, or creating rich pulsating works of sound with intense harmonic development and controlled feedback, a powerful opus of sound.
