Why do we like this?

Can't say we usually see artists releasing new tracks this late in the evening, but surprise! Band Of Horses just unleashed "Knock Knock," the first single off their upcoming album Mirage Rock.The last time we heard from the Seattle-based quintet was 2010's Infinite Arms. Funnily enough, their website still reflects a free download of the single off that album, "Factory." Looks like that's all about to change!
