There is no point reviewing the music because it has all been said so many times, suffice to say that yes, Black Sabbath's debut is compelling in extremis.
To paraquote Gillan, I don't just love it, I genuinely need it. At least once a week.
However, as is mentioned elsewhere but less trumpeted as a bonus, is the sound quality of an album made on a budget by blokes, just about in shoes but for whom at the time, laces were little more than an effeminate peccadillo.
Not just made for buttons but famously recorded in a few hours, almost in the context of a 'jam,' the clarity of what chimes forth from a decent hi-fi's speakers is nothing short of astonishing: it genuinely sounds as though you're physically present at that ubiquitous Parisienne gig (the one always shown from 'back in the day.')
If you roll forward to the next three albums where the production quality varies between all three, you have to accept a three year hiatus before 'Sabbath Bloody Sabbath' and a return to this kind of audio pleasure.
What a record; WHAT A RECORD. Sheer bliss...
