Missa Cantorem II is a guest vocal album: eleven singers from the metal world each take on one song from Call of the Wild, in the same running order as the original. The guests include Blind Guardian's Hansi Kürsch, Tommy Johansson of Sabaton and Majestica, Hannes Braun of Kissin' Dynamite, and Nils Molin of Amaranthe. The instrumental backing stays that of Powerwolf and only the voice changes, which makes it easy to hear how much a vocal style shapes the character of a song. The album originally came out in 2022, following the first Missa Cantorem that accompanied Call of the Wild. This edition is an LP.
