The brilliant, up-and-coming, underappreciated group Joy Kills Sorrow released a new EP, Wide Awake, a few days ago, and I've been listening to it on loop without interruption ever since. You could describe the ensemble as "bluegrass pop," but it might be more accurate to call them a pop group that happens to have a mandolin, banjo, and double bass. Their original songs are incredible, but the real standout on the EP is their cover of the song "Such Great Heights," which you can watch in the video below. As good as it sounds here, the studio version is even better—completely worth the dollar it costs on the iTunes Store. You can listen to some of their other music here at their website, if you need convincing beyond this video of how amazing this band is. ("Books" is the song that made me fall for the group.) Seriously, listen!
