ALT CTRL is home to the latest and greatest in alternative music. Here, it’s as much an attitude as a sound—music that keeps things a little left of center and rough around the edges. This week offers up a formidable folk-rock pairing thanks to Mumford & Sons and Hozier, whose “Rubber Band Man” sees the gents indulging in the sort of harmonizing, lung-busting choruses, and rowdy guitar-picking that made them household names.
