There are a lot of Black Sabbath compilation discs out there these days. This was the original. It was released during the original run of the band. This was originally released a double LP set. The version I'm reviewing here is the US CD. It's missing three songs from that original vinyl release. This is a good choice for a first introduction to the band. It should be noted that since I've reviewed all of these songs on their original albums, the track reviews here are copied or modified from those reviews for the sake of consistency.
