The Canadian Association of the Deaf (CAD) estimates the number of people who are "culturally deaf" — whose first native language is a signed language and who are part of the deaf community — is as high as 357,000. But when they want to go see their favourite artists perform, they can feel shut out.
In Canada, it's uncommon for venues to provide sign language services. But in the United States, sign language services at concerts and festivals is quite common. There, interpreters who specialize in music have found a following online as the videos of their enthusiastic interpretations go viral.
