When I was living in London some 15 years ago, the British Film Institute restored the silent movie, The Thief of Baghdad, and Carl Davis wrote a new score for it based on Rimsky-Korsakov's Scheherezade. I went to see a performance of it at the Dominion Theatre with the London Symphony Orchestra, and it was simply amazing to watch a silent movie with a full orchestra playing the soundtrack live. Just breathtaking.
And now, here's the same thing for the next generation - an orchestra playing in-game soundtracks live while the games themselves appear on huge video screens. I'm not sure that Mario will have the same artistic range as Douglas Fairbanks Sr., but I'm sure it'll still be must-see event. (via DoubleViking)
