DESCRIPTION:
On 1st January 2012, Shaun Buswell started a musical challenge to create an orchestra made up of musicians he met as strangers whilst travelling on the London Underground. He had until 12th December 2012 to complete this task, and then perform with this orchestra of strangers at a top London venue. Oh, and he had to write all the original music without reading a note of it.

Here's the introduction to the challenge, filmed in November 2011 by Dead Monkey Media.
