As The Killers celebrate Friday's reissue of their sophomore album Sam's Town, they've included a previously unreleased demo "Peace of Mind," which was recorded during the studio sessions for that album.

As we previously mentioned, The Killers marked the 10th anniversary of the album last weekend with a two-night set of shows at Sam's Town Hotel and Gambling Hall in Las Vegas, where fans gambled on custom, album-themed blackjack tables and Killers-inspired food items and cocktails while being treated to performances from the band.

The Killers are currently back in the studio working on the followup to their 2012 album Battle Born.
