Not my favorite ban/genre, but War Pigs especially is a stunningly great rock song.
IMO, most of the album “Paranoid” is excellent, even though in general I’m not a big Black Sabbath fan. In fact, the title track might be the 2nd weakest tune of the album, and it’s not really a weak effort...
The original CD release is, to use your word, a stunning recording from an audio standpoint, too. Perhaps partially because it is a relatively simple uncluttered mix, but well engineered, the clarity and punch / dynamics are terrific. Some of those drum rolls are just to die for, on a good audio system. A few years ago I was checking out some new-to-me computer speakers and played “Fairies Wear Boots” (album version) off You Tube. I was not impressed. But, then I popped in my old CD. BIG difference for the better. Over-compressed music (as on the CD) would not reveal a difference like that.
