Another 'music + YouTube' phenomenon is of course The Symphony Orchestra:



"Join 101 musicians from over 30 countries who make up the YouTube Symphony Orchestra 2011 playing a spectacular Grand Finale concert at Sydney Opera House.The musicians met for a weeklong celebration of music in Sydney culminating in the Grand Finale featuring animated visuals on the interior and exterior projections by Obscura Digital on the iconic sails, all synchronised to the music of the YouTube Symphony Orchestra 2011's performance and conducted by YouTube Symphony Orchestra Artistic Advisor Michael Tilson Thomas."
