I wrote this on 8 July 2011 which was a particularly thundery day in Edinburgh. I was doing an instrumental so the sound of the thunderstorm didn't bother me too much since i didn't need to use a microphone. The thunder sounded so ominous though that i just had to set up a microphone and record a track of that too.
I was recovering from a slight shoulder injury at the time, and i consider this to be a demo, but it's unlikely to surface anywhere else, so here it is, for you, now.
