Black Sabbath
Black Sabbath formed in 1968. The band was originally named Polka Tulk Blues Band. After that it was shortened to Polka Tulk. They decided after that to name themselves Earth which Osbourne hated. They played blues-rock music. Tony Iommi had a work accident that cut off the tips of his middle and ring finger on his right hand. He started tuning his guitar lower to make its strings looser. This made it easier for him to play the guitar. Because of this, his guitar had a darker, deeper sound. The band thought this made their music sound dark and scary. Their music also had unusual key changes and time signatures (metre). They released their first album, Black Sabbath, in 1970. Their most successful single, named "Paranoid" came from their second album of the same name, which was supposed to be named War Pigs. It was produced by Rodger Bain and released in 1970. After that album, they got a huge suitcase full of money so they could buy more drugs and they got more studio time.
