The follow-up to 2013's Sacrifice was produced by Andy Sneap at his Backstage Recording Studios in Derbyshire. Singer Biff Byford says: "This one's a natural progression from Sacrifice. There's a bit less rock'n'roll and a bit more 'heavy' on it. We wanted to keep focused on a style rather than moving around too much.

The band recently issued a video for the title track, which features fans rocking out at the barriers during live shows. Byford says he explores a variety of themes throughout the record.

He says: "When I'm writing lyrics I like to switch back and forth between complex things, reality and rock'n'roll. I thought the whole folklore behind The Devil's Footprint made it great material for a metal song, being that it's both historic and mythical.

"With Queen Of Hearts I wanted to write something around Lewis Carroll's Alice In Wonderland, and it's about the chess game that happens in the story. I wanted it to have prog-feeling in the way of its ambiance and mood"
