SLA proposed to locate an hybrid performance space above the Saigon river on the axis of an historical avenue. This landmark should be the magnetic point linking the old and the new city of Ho Chi Minh. Inside this theatre is a flexible place adaptable for daily touristic attraction, concert hall and symphonic orchestra. The main auditorium is an immersive space where music turn to a visual experience as the entire room is used as a giant projection screen using video mapping effects.
