"Shadowmaker" features former Scars On Broadway guitarist Franky Perez on vocals, and there's talk that the singer could become a permanent member of the group following the upcoming tour to promote the record - a trek that will see them open for Sixx AM's spring shows in North America.

Cellist Eicca Toppinen says the band wanted to challenge themselves following a year-long break. Toppinen tells The Rockpit: "It's always hard to talk about albums without being a nerdy musician. I think it's a totally new kind of record for Apocalyptica, especially because we have one singer on the whole album, and I think it's making the whole album more solid. It's more of a band record compared to the album that we have had guest vocalists, so I think it's more solid.
