Listening to your track i would be interested to see what you would do if you started to get into a few more tunes like ramstein, only because you have that kind of feel in their genre of music...
The high pitched background mixed with vocals and electric guitar
try remixes or even a cover of a few of their songs... like the song bang bang
A cover of Feuer Frei you say? That could be pretty fun if I did it right.
Please contact me if you would like to use this in a project. We can discuss the details.
