If you like horror themed electronic music, you might check out some of
my tunes here. Don't expect anything really harsh and pounding though, my tunes are pretty mellow but also dark and creepy at the same time. If that sounds like something you would dig, give some of those tunes a spin. Its all free to download as well, and most of them are in high quality wav files.
Also, if you know of any horror themed electronic tunes or artists, let me know about them. There just doesn't seem to be a whole lot of this stuff that I can find, and I am always looking for more. Thanks!
