…an examination of counterfactuals, of ‘what ifs’, of simultaneous emotional reactions where one experiences a split self.

James O’Callaghan

Enter into a world of sound, light, and video.

Mark Takeshi McGregor is no stranger to the Music on Main stage.  As one of the world’s pre-eminent contemporary flute players, he has commissioned hundreds of new pieces of music. For this very special concert, he brings together four great composers — Keiko Devaux; Alfredo Santa Ana; James O’Callaghan; and Nicole Lizée — for a sensory experience that includes lighting design by Adrian Muir.

The world premiere of Keiko Devaux’s “Hōrai” opens the concert with a mysterious atmosphere: a video fills the back wall of the theatre, invoking smoke and ancient spirits. Alfredo Santa Ana’s “Notgnirrac” is inspired by the Mexican-British artist Leonora Carrington’s blend of psychological and physical geographies.

James O’Callaghan’s “Doubt is a way of knowing” explores the ‘what ifs’ and simultaneous emotional reactions that we all experience by processing the sounds of the live flute through a second flute that acts like a speaker. And, Nicole Lizée’s “Tarantino Études” plays with damaged film and audio to reveal hidden rhythms and a death-defying sword fight between flute player and on-screen Uma Thurman.

It’s a concert that will resonate well beyond the last note.

This concert has received support from the Vancouver International Dance Festival.

This concert has received project-based support from The Canada Council for the Arts.
