The album was produced by John Feldmann and includes guest appearances from artists including Patrick Stump, Gerard Way, Quinn Allman, Ashton Irwin and Rian Dawson.

Biersack previously said of The Shadow Side: "Sonically, the goal was to really play with music and a lot of different stuff - to have a lot of odd instrumentation and to have a lot of programmed stuff, keyboards and more classic, almost pop-rock guitar. It's more U2 than Megadeth.
