Sin After Sin is the third album by the British heavy metal group Judas Priest, released in 1977. The album was remastered in 2001, with two bonus tracks added. This album featured the drum work of a very young and upcoming session drummer, Simon Phillips, who was only 19 at the time of recording. The record features a cover of Joan Baez's "Diamonds and Rust", a track that would become a live favourite from then onwards. In 1988, Slayer covered the song Dissident Agressor on their critically acclaimed South of Heaven album.
