The Killers have always operated on their own schedule in regards to making new music, but they've still released a decent amount of music over the years. Their last album release was Wonderful Wonderful
that came out in 2017. They've been working on the follow-up to that album recently, posting updates on social media periodically as they go. Their latest update is a whiteboard with an apparent list of working song titles.
The band had a similar post roughly six months ago, however the two boards don't share any common song titles.
The Killers' are currently working in the studio on their sixth album. There is no official release date for the record but fans should expect to see an album be released in 2020.
