Primus Much?
You wouldn't happen to be an illegitimate love-child to Les Claypool, would you lol? It's very different music, but it shows a lot of competence. Given some real studio time, I have a feeling you'd be making some really intense stuff. Like the below guy said, there are some issues with the volume on some instruments, but the overall idea sound good to me.
5/5 for concept, 3.5/5 for execution. So, pretty good in my opinion :D. If you can go back and tweak some levels, I really would advise it. I can't tell if it's keys or percussion at the end, but that little bit of a hook at the last 15 seconds or so is really really cool. I'd love to hear it brought out more.
Oh, and you should post the lyrics. They sound pretty amusing when I can make them out :D
