Now THIS is ‘metal done right’ from the heyday of truly great world-class hard rock/metal. Heavy, bombastic, plodding, gritty, dark, impending doom only as Black Sabbath can deliver. Everyone else is a pale substitute. Ungodly riffing and emotive lead guitar excursions by the ‘high priest’ of metal guitar himself, Tony Iommi. At age 44, I still listen to this masterpiece a quarter of a century after it was released with my jaw agape. Talk about ’standing the test of time’! Long live Black Sabbath!
