What we have here is Reyn Ouwehand performing a fabulous modern version of the "Green Beret" theme by (the great) Martin Galway.  It also happens to be an excellent example of what a single talented musician can do with a handful of instruments and a loop machine.

For those that don't know, Martin Galway was one of a small group (along with Rob Hubbard, Ben Daglish, and David Whittaker) of music composers / programmers that became celebrities within the (admittedly niche) Commodore C64 gaming community.

They, along with a few other 'names' from the same period were one of the reasons I got into computing in the first place.

Anyway... sit down, put your headphones on, and spend the next 10 minutes listening to this; if you like electronic music I think you will love this.
