Heaven and Hell is an album by Black Sabbath, released in May 1980. This was the first album after the removal of singer Ozzy Osbourne from the band and was the first album featuring Ronnie James Dio , formerly of Ritchie Blackmore's Rainbow , who brought his own unique style of song writing and vocalisation to the band. With the changing of singers, a change in songwriting approaches, and the sound crafting skills of famous heavy metal producer Martin Birch, the band altered their trademark drudge rock to a faster, slicker and more melodic sound.
Other notable tracks are "Neon Knights", "Children of the Sea" and "Die Young". Heaven and Hell remains one of Black Sabbath's best-selling albums, and was their highest charting album (#9 UK, #28 USA) since 1975's Sabotage. The album revitalised Sabbath's fortunes after what many saw as the death of the group following Ozzy's departure.
