I just realized...

Angel Witch, Satan, and Pagan Altar are fucking good. I always listened to a lot of traditional metal and NWOBHM, even though I primarily listened to extreme metal (particularly black metal).
 
I sometimes go through this... usually when I listen to to much brutal death. It becomes grating. The thing is, I don't have any non metal to listen to... so I just listen to black metal instead (the more melodic stuff, usually with acoustic bits).
 
I can't decide whether Let Mortal Heroes... is hypnotizingly beautiful or RPG soundtrack lame :(

But then it's the only Summoning I have, Dol Goldur has been on the wishlist for a while.
