When Black Sabbath initially unleashed 'Vol.4' in the Autumn of 1972, my ears were probably too occupied with the recently released T.Rex masterpiece 'The Slider' to notice the kerfuffle. I came to 'Vol.4' a little later and it's always been my favourite of The Sabs' albums, though the follow up, 'Sabbath Bloody Sabbath', runs it mighty close. I saw the classic Ozzy-led line-up just once, a little after their prime perhaps, but they were still an impressively thunderous live prospect.
