In 2015, Nathalie Warmerdam was murdered by her ex-partner. She was one of three victims that day; he also killed two other former partners, Anastasia Kuzyk and Carol Culleton. Basil Borutski was found guilty and sentenced to life in prison in 2017. Now as a way to deal with his grief, Nathalie's brother, opera singer Joshua Hopkins, has released a group of songs, known as a song cycle, in memory of his sister. With words by the writer Margaret Atwood and music by composer Jake Heggie, Joshua says he wants to use his voice to raise awareness about violence against women.
