I'm listening to Nema right now. Here are my play by play comments on it.
Intro: Very interesting intro, one would expect an electric guitar to be over it, but it isn't... VERY cool twist
Enter clean vocals: I don't like the clean vocals. May differ from person to person... just doesn't grab me. A better attempt than I could do, though.
Enter growls: I like the growls!!! Very cool
Very nice melodic section at 1:36. the build up for it was pretty cool.
The drums sound electronic in the part after that. Are they? Doesn't matter to me. Very nice sounding instruments and production.
Piano solo. Simple, yet effective!
Those weird ass background vocals in the next part... Took the first 4 seconds to get used to them. A little disturbing, but perhaps that's the feel you wanted them to be.
The same elegant piano solo over some intense black riffage was very nicely done, IMO.
All in all... I think you have a pretty solid band over there! Best of luck in the future, and best of luck with anything you wish to accomplish. I'll get the other 2 songs, and will most likely listen to on a regular basis. Great job.
