A couple of songs I’m humming on these days:

Avalost by Seabound, from No Sleep Demon v2. Sorry about the cellphone quality, this song deserves better. (Here’s Transformer, another good song from the same album.)

In the same vein, but more anthemy, Ritual Noise by Covenant, from Skyshaper.

And on a lighter note, Mind of God and Tune Up by Electric Universe, from Silence In Action.
