2112 by Rush. The first always has a permanent place in your heart. I remember hearing for the first time Neil's sticks hitting the edge of the drum and thinking "wow, this is new and exciting!" The whole experience of hearing a long single theme piece that goes up and down like a breathing organic thing completely shifted the way I was going to listen to music in the future. And words that mean something...
"See how it sings like a sad heart and joyously screams out its pain. Sounds that build high like a mountain or notes that fall, gently like rain"
