SPACEDOUT reimagines the concert hall as a welcoming space where listening can happen in different ways. Images reveal the stories within the music, while movement, touch, and vibration bring audiences closer to the performers. Listeners are free to enter, leave, make noise, or join the quartet on stage, even sitting among the musicians to feel sound being created around them. Designed with attention-related conditions in mind, the experience opens classical music to everyone without separating audiences.
