This really surprised me. I was expecting a heavy metal song, like the genre said, but got something completely different. I'm guessing that was a slip of the hand?
This had a really relaxed feel to it, but it was very driving at the same time. The parts blended together really well, so I applaud you for that. And they also created a really nice atmosphere.
One thing is that it does get a bit repetitive after awhile, even if it is still pretty cool. Would have liked to see a little more variety in there. That would have made it much better in my opinion, either that or just cutting it a bit.
Sorry I can't offer up a whole lot more of advice, not that great at giving feedback. However, would you mind checking out my latest song? Thanks!
