Black Sabbath's Recording History and Song Details

Black Sabbath achieved their first Top 10 album in the United States with Master Of Reality. At the conclusion of their United States tour, the band members were given a three-day break. This break took place before they were scheduled to perform two upcoming concerts at the Koseinenkin concert hall located in Osaka.

For their residence, the band rented a luxury mansion in Bel Air from John Dupont, who is an heir to the Dupont company. This rented house included an Olympic swimming pool as well as a large ballroom. The band utilized this large ballroom as a space where they composed and played their music. The actual audio recordings of the album were then carried out at Record Plant studios.

The album Vol 4 starts with a track titled Wheels Of Confusion, which exceeds eight minutes in length. Within the album, the song Changes features Tony Iommi on piano, while Geezer Butler used a Mellotron for the track. Furthermore, the band adhered to a specific rule of not releasing more than one single from an album. Following this guideline, they chose the song Tomorrow's Dream as the single release.
