Bring on the skronk. The vocals are pure torture, and one of them's found a silly clown noise on his keyboard, but all the Hi-NRG dancefloor drumming's still in place. Sweet.

This is so massive. It's humungoulous. For every stolen Sabbath riff there's a heavy dose of dilated-pupil sky rocking to balance it all out.

Sleep's rhythm section stretches out on two 15-minute dudefests with minimum instruments yielding maximum satisfaction.
