The work will be premiered this weekend in his home town of St Ives during the run-up to the Riverside Gala the following week.
Guitarist David, 48, who had formed a music career in London, had just moved to St Ives when the terrible accident happened on February 15, 2006.

Waving a friend farewell on her train back to London, the automatic doors closed and trapped David's coat between them.
Locked in the metal jaws, David was dragged along the platform and finally underneath the wheels of the moving train. What happened next changed David's life in more ways than one and inspired him to write his first piece of classical music.

While bleeding heavily from his severely injured left arm, at Addenbrooke's Hospital, David had what he can only describe as a near-death experience.

He added: "It's happened to lots of people who have come near to death. It was a very spiritual experience, where I left my body and felt like I had gone onto the next place.

"All the agony I was feeling from my accident at the time disappeared when I was in this place. I felt an overwhelming feeling of love. It's changed my whole view on mortality and immortality."
When David finally came round the first thing he asked for was a pen and paper, so he could write down his experience and share it with others.

But for musician David, writing just wasn't enough.
Having played the guitar from the age of 12, and starred as the opening act for top bands Fine Young Cannibals and The Beach Boys in the 1990s, expressing himself through music seemed the obvious answer. But after three weeks in hospital and three major operations, that wasn't so simple.

David added: "Due to the injury of my left arm, I am no longer able to play the guitar.
But ultimately the music was still in me and I still wanted to express myself through it."

So with the help of his classically-trained brother Ian, who plays the French horn for the Westminster Philharmonic Orchestra, David wrote a symphony on a synthesizer – an electronic instrument capable of producing a variety of sounds by generating and combining signals of different frequencies.

And after a year of hard work his symphony, The Divine Light, was born.
David added: "The response has been so positive that I'm really quite taken aback by it all.
"There are obviously people who are going to have a scientific point of view to near-death experiences. I'm not here to preach about what happened to me, I'm just here to talk about it.
"All I'm trying to say is this is what happened, this is what I saw and I hope it gives people faith."

>> The Divine Light will be premiered on Saturday (July 12) by The Chamber Orchestra of St Ives, at The Free Church, St Ives at 7.30pm.
