Powerwolf played a headline set at Summer Breeze Festival in 2015, a significant performance that featured the band's first-ever use of augmented reality (AR) during a live concert, creating a large wolf above the stage that was visible to both the live audience and those watching the livestream. This performance was later released as part of their live album "The Metal Mass – Live," which documented the show alongside other concerts from the same year. The setlist included hits like "Army of the Night" and "Amen & Attack".
