Jonathan, you mentioned goose bumps or chills quite a bit at the blind speaker GTG over here, the songs were Dead Boy's Poem by NIghtwish (female vocals) and the last minute of Resurrection by Fear Factory.
Yesterday I played (see if I can remember):
Nevermore - Believe in Nothing
Nightwish - Ghost Love Score
After Forever - Beyond Me (love the soprano mixed with growls all to a tune that sounds like it belongs in the movie Gladiator)
Avenged Sevenfold - Save Me (Mike Portnoy from Dream Theater on drums, Tim, you said you like this one)
Hypocricy - The Arrival of the Demons
Type O Negative - Nettie
Ok, don't me started discussing music we know where that leads.
