Rated 6/10
Alright, so this is definitely something indeed. Heavy - yes, but also this is basically a blues album and I still think Sabbath earns the cake for the first metal album. But of course, this is very good, at least 3 stars for sure, and at least 3.5 on RYM, I imagine if I was rating this when it came around in 60s it would have a much bigger rating, but a lot has happened since then!
