New demo song

[Rickocaster]

Okay, first, I really like this and think you should go ahead with it. I wasn't expecting the heavy stuff so it was a great surprise and it really works.  I definitely think this needs a vocal part - there's a message in there just crying to be released!

This is more of a question than a suggestion, but just before the song loops back to repeat there are some changes in there that clash. Maybe it's intentional, and if so, I would shove it in our faces with a little more volume or distortion. If not, you might experiment with some different changes.

I also agree with the other suggestions listed. I really hope you keep working on this and post it again. This song rocks!
