This one is still very much in progress. The song is currently entitled "For My Antiparticle", and it's based on the idea of quantum foam. The general gist of quantum foam is that in the emptiest regions of space, there are particle/antiparticle pairs constantly popping into existence out of nowhere and then almost instantly annihilating one another. One imagines that if a fundamental particle was capable of thought, its last thought would be something like "what in the hell was the point of all this?", and that's exactly what this song is about.
The recording is rough, but it captures most of what I want to get out of this one. I'll probably just do a bit of tweaking and maybe redo the vocals and drums at some point, but I think it's bearable as is.
