Although singer/songwriter Amos Lee often comes across as apologetic with his nearly whispered vocals, his newest effort, Supply and Demand, ?nds him sounding much more self-assured, and the lyrics to the disc’s opener, “Shout Out Loud,” are every bit as af?rming as a ?st-pumping arena-rock tune, with Lee even breaking out of his normally hushed singing on several tracks. Sure, this onetime schoolteacher still exhibits moments of repentant introversion—such as the aching, done-me-wrong ballad “Careless”—but his incorporation of gospel, soul and blues elements into his stripped-down folk music, as well as his newfound optimism, make Supply and Demand a welcome change of pace.
