The Sacrament of Sin is the seventh studio album by German power metal band Powerwolf, released on 20 July 2018 by Napalm Records. The band wrote it during 2017 and began recording it in January 2018 at the Fascination Street Studios in Örebro, Sweden. It was Jens Bogren's first production work for Powerwolf. Joost van den Broek assisted the band with orchestras. Musically, the album is much more different than previous recordings. The expression of the organ has changed, the orchestra has been added and unusual elements such as bagpipes or flute and the band recorded a ballad accompanied by the piano for the first time in its history. The main theme of the album from the point of view of lyrics is sin, but it is not a concept album.
