I have Cold Steel... For an Iron Age and seen them open up to Behemoth in 2002 or something. They remain a secret favourite, just all out aggression and catchy as hell. Now listening to the Grateful dead - Dark Star from the Fillmore East at 2-11-1969. But because that sounds too Deadhead-nerdish I'll go with Lunar Aurora - Geist der Nebelsphären. I love that band so much I could just crap.
"Skol Blues" - Alex Skolnick Trio ...Oh wait I'm in the metal boards. *goes to find a metal track* "The Dark Eternal Night" - Dream Theater (One of my favorite metal tracks at the moment).
