As you probably know, the YouTube Symphony — a collection of 96 musicians from more than 30 countries who were selected via online voting — made its debut performance Wednesday night at Carnegie Hall in New York. The verdict on the three-hour concert is starting to trickle in (The New York Times, for instance, admired the performance but wished it was “less gimmicky and more substantive”), but YouTube has already posted a video of the concert’s first act, so you can now decide for yourself. What do you think, PopWatchers? Is this an inspiring 21st-century experiment, or a haphazard attempt at corporate public service? (And, YouTube, why oh why is this vid not available in HD?)
