Jennifer Nettles’ voice can hold its own in any setting, but exceeds expectations alongside partner Kristian Bush’s mandolin strumming at the Grainger Studio. During this sensational hour, Sugarland presents a versatile set that gains momentum with each song. “Joey” is heartbreakingly sincere, “Everyday America” reveals strong, twangy vocals while broken-down acoustics give “Stay” a more traditional country sound. Their forte is to effortlessly transition from energetic pop songs to heartfelt, soulful ballads without skipping a beat. The dynamic duo also present older classics like “Baby Girl” and even venture into covers of R.E.M to pay homage to shared Atlanta roots during their set.
