“Sigh No More,” the debut album by U.K. folk-rock band Mumford & Sons, focuses strictly on group harmony, making the sound more dynamic.

Listeners will hear a strong influence from Americana through the acoustic instrumentation and heavy banjo use.

The standout songs on the album — “The Cave,” “Winter Winds” and “Little Lion Man” — are sung with fiery emotions. While not deep lyrically, the listener can feel the emotion as singer Marcus Mumford belts each chorus.

There are a few songs on the record, especially near the end, that are too soft. While the album begins with a roar, it ends with a whisper.  “After the Storm,” the final track, is too subtle and leaves listeners wishing the band had added more to the track.

While their debut may not be perfect, Mumford & Sons show they have the passion and impressive harmonizing ability to keep fans interested.
