Sin After Sin is the third studio album by English heavy metal band Judas Priest, released on 8 April 1977 by Columbia Records, and on 22 April in the UK, by CBS Records. Produced by Deep Purple bassist Roger Glover, it was the band's major label debut, their first album for the label, and their only album to feature drummer Simon Phillips, a studio musician who replaced drummer Alan Moore for the recording sessions. The album continues the revolutionary direction the band first took on Sad Wings of Destiny, this time incorporating elements that would later define thrash metal and speed metal, particularly on the songs "Let Us Prey/Call of the Priest" and "Dissident Aggressor". Despite this, and positive critical and commercial reception, the album has failed to achieve the acclaim Sad Wings of Destiny and their follow-up album, Stained Class have received.
