Black Sabbath going strong – very much in their own space by this point in their career, setting a sound that countless others would try to follow – but never match for fierceness like this! The fuzz is definitely turned up to 11, the rhythms move at a breakneck speed, and Ozzy's vocals have all the mean, sinister sounds that set a generation on fire – plenty of energy to fill up long tracks that include "Megalomania", "Hole In The Sky", "Symptom Of The Universe", "Supertzar", "Am I Going Insane", and "The Writ".
