This southern family band — siblings Natalie, Stacey, Isaaca, and Jeremy Byrd with cousin Brittany Painter on lead vocals and guitar — pull together a pop-rock-folk-country sound that draws its influence from a variety of obvious and obscure points of reference. The tight, flowing harmonies on this debut album recall Fleetwood Mac and Crosby, Stills and Nash, while the songwriting ranges from traditional pop (“All the Words”) to the askew piano drama of a Fiona Apple type chanteuse (“Blue”). Produced by alternative pop veteran Matthew Sweet with an emphasis on their vocal graces, the Bridges use their southern charm — North Carolina to Alabama — to put listeners in the easy chair, ready to recline with these effortless, lush pop confections. The constant vocal motion behind “Echo” displays the quintet’s musical sophistication without losing the simple melodic thread. They’re such natural, intuitive singers that they can’t help but sound smooth and polished. “Finding It Hard,” “Pieces,” and “Under the Sun” naturally shade towards easy listening. The Bridges are surprisingly mature for such a young group.
