Very impressed.
I guess I should stop being impressed by finding gems on the NG Audio Portal by now, seem to come around more often than not.
This is a really, really good track. It has this grand feel to it, and it's very well written. The rhythmics are great, no lack of originality or large amounts of boring repetition, and in general the track is varied throughout, which is always a good thing, IMO.
The track has this ambience to it, it feels very expansive and large and rather soothing and relaxing. The melodic tracks of the guitar is really good, and definitely part of what makes the track so relaxing. I doubt it fits very well in Heavy Metal, but I wouldn't know where to put it myself.
Get working on another track and see if you can't throw in some vocals too.
