Arriving as something as a surprise, Colbie Caillat’s Gypsy Heart Side A—EP has the feel of a personal statement as well as a summertime pop treat. In these five tracks, the singer/songwriter reconnects with the easygoing California vibe that earned her a loyal following in the first place. “Live It Up” hits the right note with its percolating groove and joyful chorus, delivered by Caillat with slinky sweetness. The momentum continues with “Blaze,” an upbeat anthem that invites one and all to dance barefoot on tables and sing out with abandon. Caillat tacks in a sleek electronica direction on “If You Love Me Let Me Go,” a pre-breakup tune that avoids spite in favor of understanding. If there’s a standout here lyrically, it’s the ballad “Try,” a heartfelt commentary on feminine self-image framed by a lean R&B-tinged arrangement. The uplifting, countrified “Never Gonna Let You Down” wraps things up with a pledge of enduring friendship spurred on by a clap-along beat.
