For a week in July, the best opera in Canada was halfway up an Alberta mountain. True to its 1930s origins as an “Experimental School in the Arts Related to the Theatre,” the Banff Centre for the Arts and Creativity presented two ambitious workshop productions,
a Mozart murder-mystery collage called No One’s Safe, written and directed by Joel Ivany, and Britten’s Rape of Lucretia, directed by Paul Curran.
