Meet Grammy-winning American composer and conductor, Eric Whitacre. Although you might not have heard of him before, The Daily Telegraph has called Whitacre a "rare thing, a modern composer who is both popular and original."
He has won numerous awards for his work, including awards from the Barlow international composition competition, American Choral Directors Association, American Composers' Forum.
But that's only half of the story.
By combining his choral, orchestral and wind ensemble music, the power of the Internet and thousands of talented strangers- as well as Whitacre's determination- his Virtual Choir projects have pushed the boundaries and inspired the world.
I will let him explain the concept in this 2011 TED lecture the rest of the details.
