The title follows 2010's Ziltoid The Omniscient concept album, which introduced the world to the alien title character. Townsend says: "Z2 is a double album, one side Devin Townsend Project and one side Ziltoid. The concept expands on his sci-fi adventures in a way that kind of throws back to 1950s radio plays - but obviously with heavy, complicated music as its soundtrack.

"It's taken a great deal of energy to pull this all together. It's a dream come true in a lot of ways and I'm excited to finalise the project with a live version of the record at the Albert Hall. Basically, what we did with The Retinal Circus a few years back will be taken to the next level with Z2 Live."
