Is it a concert, is it technology, or is it an art show? Multimedia artist Gordon Monahan has combined all three disciplines and a bit more into When It Rains.

He describes the show as "an interactive computer and mechanical sound sculpture installation." Monahan is a Canadian artist now living in Germany, who's returned for this unique Millennium program. He's been working on these kind of soundscapes since studying with John Cage for two years in the 1980s, and his 1996 show, Spontaneously Harmonious in Certain Kinds of Weather, pulled much of his weather work together.

Gallery One2One helps us understand the new exhibit: "Monahan's homemade sculptures play pre-programmed musical sequences, triggered by data input from audience members. The data is processed through a computerized, random decision-making-process that determines which sequences are played and how many sequences are layered upon each other."

Monahan, who received a Music Canada Musique 2000 commission for this, has worked with the assumption that music has always existed in nature. He imposes technological control over these natural, musical sounds "in order to question our assumptions of what music is, and where it comes from."

The program continues until Saturday, Nov. 26 at the Toronto gallery,

Popera:
Opera Ontario is considered one of the finest regional operas in Canada, combining the operatic societies of Hamilton-Wentworth and Kitchener-Waterloo into one organization. Last year the Toronto Star wrote that "it's worth travelling some distance" for the shows. Tonight they're putting on a rush-seating Popera concert at Centre in the Square in Kitchener. Not much info on this... it's an annual event that features an "outstanding international cast to perform your favourite overtures, arias, and ensembles from some of the world's most fabulous operas." They're got a cool "Flash" intro on the homepage, but not a lot of other details on shows. Mysteriously, though, they claim to have won three web awards already for their otherwise empty site.
