A few weeks ago, Band of Horses hit us with a teaser video for their new album which still left much to the imagination and had fans eagerly awaiting more details. Finally, those details have dropped — and in mass amounts. Not only have the band announced that Mirage Rock will drop September 18, but they've also released album art, tracklisting, and a new song, "Knock Knock." It's a hand-clappy, pop-tinged jam loaded with sunny melodies and soul-swelling instrumentals, confirming what we've all come to anticipate — Mirage Rock promises to be another solid album. Pre-orders are available now via iTunes, and each comes with an instant download of "Knock Knock" as well as an exclusive, pre-order only track, "Ego Nightmare." Spin the song, get your pre-orders going, and check out the full tracklisting below.
