On their studio albums, the Gaslight Anthem have worked out a kind of perfect ratio of earnestness and enthusiasm as they breathe new life into the rugged heartland rock of greats like Bruce Springsteen.

With The B-Sides, fans are treated to another side of the band with a collection of live tracks, acoustic versions, covers, and unused studio cuts.

While you could always describe the band's sound as raw, there's a sense of practiced composure on their albums that's refreshingly absent from the acoustic home recordings of "The Queen of Lower Chelsea" and "Boxer." Elsewhere, the Gaslight Anthem take a stab at the songs of some of their influences, offering up a ripping live rendition of Pearl Jam's "State of Love and Trust" alongside a cool and loose cover of the Rolling Stones' "Tumbling Dice," showing that there's a lot more to their sound than their Garden State roots.

The collection's most stirring moments come from recordings culled from the American Slang sessions.

Album-opener "She Loves You" (originally a bonus track on the deluxe edition of American Slang) substitutes drive for a slow burn as the band plays around with atmosphere, creating a track that feels oddly ethereal despite its marching backbeat.

One of that album's more stirring numbers, the titular "American Slang," also makes an appearance on the album, with a stripped-down arrangement that pares the song down to just acoustic guitar and vocals, transforming the song into a more plaintive, downbeat number as it exposes the raw emotions that live at the song's center.

Changes like this provide a new angle to the songs of the band's strongest albums, making The B-Sides a collection that Gaslight Anthem fans will want to dig into and explore.
