I think that the music is by L Mckennith (similar to Clannad and Enya) I don't know which track If anyone finds it could they post it here as I'd like to get a copy as well.
To see more details of his amazing videos look at Lionel Charlet's site at

The DVDs don't seem to be available in the UK but can be ordered over the net.
