A non-musical symphony.
Deaf mute performers?
@FrayedBear M Waff thanked the performers audibly and without signing.
@FrayedBear Deaf mute performers with the “greenest” of instruments.
@p-nullifidian my comment is tongue in cheek. The performers are not using any sign language that I know. But then Australia is peculiar & unique in its Auslan.
Incredible! Vive la France! Thank you for this.
