I’m certainly not a fan of metal. Most of the time, I find it all too loud, dark and simplistic, not to mention clichéd. Then again, perhaps it’s because I discovered Black Sabbath at a very early age. For me, they practically defined the genre, which has left me rather jaded when it comes to most other metal and hard rock acts. Everything about this album is spot on: the guitar riffs, the driving rhythm section and the surprisingly thoughtful lyrics. Even Ozzy’s whiny voice fits perfectly. It's a milestone that remains as captivating as ever, even after 56 years.
