Wow. Couldn't name one. Although my tastes in music are incredibly narrow, potentially bordering on niche. Also, @LeisureSuitLoli, not even a (small) hint?
#3 Candlemass - Solitude #5 Agalloch - In the Shadow of Our Pale Companion (one of my favorite bands ) You stumped me on the rest... I guess I'm a little rusty on my metal
Theres not even a notice of that kind, they just edited in random guitar noises. German "Gema" is so crazy!
