CBC: Evolution is evolving — the CBC Radio-Canada composers competition gets underway this week at the Banff Centre. Five young Canadian composers selected to write pieces for one ensemble — competing for the $20,000 National Composition Grand Prize among other awards — are now settling into their ‘huts’ to write.

You can hear from the composers themselves throughout the week on “The Signal” (10 p.m.), leading up to the special live broadcast of the finished works on March 26.

They’ve also been blogging over on the Evolution website.

Four of the five Evoution finalists have works that are currently available online at Concerts On Demand: David Adamcyk, Geof Holbrook, Andrew Staniland, Vincent Ho.
