Excellent selection. I'm glad you included The Number Of The Beast there at the end.

I would inlcude these:

Black Sabbath - Master of Reality

Metallica - Master Of Puppets (arguably the best metal album ever)

Radiohead - OK Computer

Public Enemy - Fear Of A Black Planet

QOTSA - Songs For The Deaf

Tool - Lateralus

Nada Surf - Let Go

Kyuss - Welcome To Sky Valley

Slayer - Reign In Blood

Smashing Pumpkins - Mellon Collie ...

Sloan - One Chord To Another
