The album marks Tate's first release since reaching a legal settlement with his former colleagues in Queensryche. The Key is the first in a trilogy of records that explores "international politics, the world economy and social ethos."

Tate says: "We've thrown out the rules for this record, and it's been really liberating. I'm a fan of old prog, and that music didn't stick to rules. It's inspiring and enjoyable to be able to explore, and it's great being in a position to write without constraints."
