In a word, awesome! Last week I had the pleasure of visiting Cardiff's works on display in Montreal. Her work which stuck me the most, and is relevant to this forum, is her "Forty-Part Motet". Basically, it's a large room with 40 B&W 303 speakers on stands, forming a circle, pointing inward. The speakers are grouped into 8 sets of 5, each representing a different choir. In most cases, each speaker represents a single voice. All the choirs are collaborating to sing "Spem in alium" by Thomas Tallis, a 16'th century work. The listener is encouraged to walk around the area, either listening to individual voices, or taking in the work as a whole. It was an incredible surround sound experience. We spend more than an hour in the room, just listening in awe! I just need to get 35 more speakers... If you ever get a chance to visit this work, I highly recommend it!
