Black Sabbath, 'Master of Reality' - 500 Greatest Albums of All Time
Black Sabbath, 'Master of Reality' - The greatest sludge-metal band of them all in its prime. Paranoid may have bigger hits, but Master of Reality, released a mere six months later, is heavier. The highlight is "Sweet Leaf," a droning love song to marijuana. But the vibe is perfectly summed up by the final track, "Into the Void."
