Sound — 10
People say Led Zeppelin or Deep Purple started metal but those bands are not metal bands, Black Sabbath started the whole thing and this is the 1st metal album. This got other bands to use distorshin in thier guitars. There would not be Metallica, Slayer, Pantera, or Hatebreed if this album wasnt released. This has everything, Ozzy's gloomy singing, Tony's heavy guitar, Bill's fast drum solos or Geezer's distorted bass.

The lyrics are pretty good and it fits the music well. Ozzy is a great singer but his voice sounds a little different on this album, still good though.
Overall Impression — 10
This may not be better than Parinoid but this album still kick ass and it has been 30+ years since its release and still sounds heavy today. The best songs are Black Sabbath, Behind The Wall Of Sleep, NIB, and The Wizard. I love this album beacause it stook out from the rest back then and no one else sounded like that and that was when metal was born. So go get this album now.
