What is "tornrak"

Tornrak is the third opera by Welsh composer John Metcalf. It has an English-language libretto by Michael Wilcox with Inuktitut sections translated by Blendina Makkik. Set between the worlds of the Canadian Arctic and Victorian Britain, it features Inuit throat singing and other extended vocal techniques that give the Arctic scenes a distinct character. The opera was composed between 1986 and 1990 when Metcalf was working in Canada. It was first staged in 1990 in a co-production by the Banff Centre, where Metcalf worked, and the Welsh National Opera who had commissioned the work.
