A modern Opera adaptation of the Oscar-winning film Brokeback Mountain premieres in Madrid this week.

Based on the short story by Annie Proulx, the tale of forbidden love between two cowboys has been translated into an opera.

Composer Charles Wuorinen completed the opera in 2012 after exploring the Wyoming mountains with Proulx, who also wrote the libretto for the opera.

Proulx spoke to Kirsty Lang on Front Row.
