English singer-songwriter Sienna Spiro has had a remarkable rise since releasing her debut single in 2024, charting worldwide with a string of hits and receiving critical acclaim including nominations at the BRIT Awards and the American Music Awards.
One of her most talked-about performances was a full orchestral set at London's Royal Albert Hall, staged as part of the celebration of David Attenborough's 100th birthday — a moment that introduced her to an even wider global audience.
Backed by over a billion streams, Sienna Spiro is now taking her music on the road across North America. Her Montreal date takes place at L'Olympia on Friday, October 23, 2026, with doors opening at 19:00 and the show starting at 20:00.
