The AGO is currently hosting a fascinating set of works by artists Janet Cardiff and George Bures Miller that incorporate music, sound, video, sculpture, robotics, lighting and other special effects. "Lost in the Memory Palace" consists of a series of eight rooms, each containing a playful installation that stimulates your eyes, ears and brain and often blurs the lines between reality and fiction.
simultaneous but relatively independent melodic lines. For the "Forty-Part Motet" installation, Cardiff commissioned eight choirs, of five members each, to sing the forty parts of the motet Spem in Alium by Thomas Tallis (1593). Eight groupings of five speakers were then positioned in an oval within the Henry Moore sculpture gallery, with each speaker projecting one of the recorded voices. If you walk up to a grouping of speakers, you can clearly hear the individual voice in each one. Sitting in the middle of the oval results in an angelic concert in surround sound, made all the more poignant while viewing the beautiful Moore sculptures.
The other three installations are equally interesting. The uniquely interactive, "performance-art" experiences of this exhibit are so much fun and not to be missed.
