It was written by renowned Chinese composer Tan Dun for the youtube symphony orchestra.
Unconventionally, Tan Dun has included drum brakes and rims from automobiles as additional instruments. Tan Dun also embedded a main theme of the first movement of Beethoven's Symphony No.3: Eroica into his work.
Hope you peeps would enjoy this wonderful composition as I did. ^^
This is how the youtube symphony orchestra was built through auditions on youtube. A perfect concept to get people together from around the globe.
