The runaway debut from the little Denver folk band that could

By the conventional wisdom of the '10s, this album is an anomaly: There's no Auto-Tune, no drums, and hardly any production at all. You can even hear the room echoes when this acoustic band strikes up a sing-along chorus. Two immensely catchy singles, "Ho Hey" and "Stubborn Love," got The Lumineers noticed, but the album gets its staying power from subtler tunes like "Slow It Down," which makes effective use of Neyla Pekarek's cello. Heartfelt, uncluttered performances of terrific songs? What a concept.
