Sam Phillips has never been afraid of musical exploration, and on her 15th album, she ventures into uncharted territory with gusto, her ‘60s-spiked, sun-kissed pop nodding to Brill Building-era greats while managing to sound as fresh as a daisy. She plays with analog recording and vibrant percussion on doo-wop-inspired rocker “Pretty Time Bomb,” while “When I’m Alone” is a shuffling, skiffle-laced ode to independence. And “Going” charts a literal and metaphorical journey, the swinging waltz beat and sweet vocals driving Phillips onward.
