Missa Cantorem II is a follow up to Powerwolf’s album, Missa Cantorem, that was released on the special edition of Call of the Wild. It is released along with the start of the band’s tour of Call of the Wild. Like the original Missa Cantorem it features a cast of guest singers from all across the subgenres of metal. Unlike the original that was a collection of the bands earlier releases, this version is the full track list of Call of the Wild.
