With her deep, throaty vocals and evocative lyrical slant, Sam Phillips has been a commandingly idiosyncratic alt-pop songsmith ever since transitioning from Christian music in the late '80s. Often produced by then-husband T Bone Burnett, she could unspool delicate, acoustic chamber-folk waltzes like "Reflecting Light", travel back to the '60s with psych-pop rockers like "Holding On To the Earth" or launch into swooping orchestral-pop pieces like "Where the Colors Don't Go" with equal amounts of grace and elan.
