Here’s the Youtube Symphony Orchestra, the first ever online collaborative orchestra, performing at Carnegie Hall on April 15th 2009. The orchestra was composed of 96 professional and amateur musicians from 30+ countries and territories on six continents and represented 26 different instruments. The orchestra played movements and excerpts from 15 wildly diverse works for over 59 minutes, but opened up the evening with Tan Dun’s Internet Symphony No. 1, “Eroica.”
