Led by Minnesota native Adrianne Lenker, Brooklyn’s Big Thief have become something of a breakout indie act over the past year, though not by making grand gestures. Instead, the four-piece create folksy indie rock that grows on listeners—a characteristically subtle, quiet Big Thief song might seem like background music till wiggling its way into your head or wrecking you emotionally after a few more plays. Lenker and guitarist Buck Meek had worked together for a couple records before the pair formed Big Thief and made their acclaimed debut, Masterpiece, on Saddle Creek Records last year. They quickly followed it up with Capacity, released last month. Recorded while Big Thief lived together on an upstate New York farm, the dense full-band songs have a palpable, intimate chemistry, while Lenker, an exacting singer and specific lyricist, shines during solo moments. Twain open.
