The gala for the Polaris Music Prize, an annual award presented to the best Canadian album, will take place on Sept. 29 with live performances by nominees including Vancouver psych rockers Black Mountain and Ottawa alt-country singer Kathleen Edwards.

The gala is being held at the Phoenix Concert Theatre in Toronto and will conclude with the announcement of this year's $20,000 Canadian ($19,089) Polaris Music Prize. Other acts playing include Basia Bulat (London), Kathleen Edwards (Ottawa), Holy Fuck (Toronto), Plants And Animals (Montréal), Shad (London), and Two Hours Traffic (Charlottetown).

Steve Jordan, executive director of the Polaris award, said the acts playing represent the spectrum of Canadian music.

"Individually, these artists cannot be neatly categorized," he said. "But it's safe to say with instrumentation that touches on country, heavy rock, psychedelia, punk, folk, rap, electronic, dance and beyond that this will definitely be the most musically diverse gala in our short three-year history."

Other nominees, including Stars (Montréal), Caribou (Dundas, Ont.) and The Weakerthans (Winnipeg), will be represented by exclusive live video performances. The gala is being hosted by CBC Radio 3's Grant Lawrence and will be broadcasted live across North America on Sirius channel 86, and around the world on the web at radio3.cbc.ca. It will also be shot for a future television broadcast on CITY TV stations across the country.
