A collaboration between YouTube, the London Symphony Orchestra, and several global partners, the YouTube Symphony Orchestra is a musical event created through open auditions worldwide. Launched in 2008, it is the first-ever online collaborative orchestra.

For the 2011 Grande Finale Concert, conducted by San Francisco Symphony conductor Michael Tilson Thomas, Obscura undertook one of their most ambitious projects to date: mapping the interior and exterior of the sweeping structure with visual projections linked to the live orchestral performance. The edifice itself became a performer in the musical celebration, with real-time audio-reactive visuals that danced and flickered and radiated across the building’s surfaces.

Over ten years of Obscura’s technology innovations culminated in the two-hour show, which brought people together from all over the world. The event was an opportunity for established musicians and emerging talent to celebrate their accomplishments and love of music.
