Marvin Gaye is grinning from his grave these days. Socially conscious, emotionally rich music delivered from the heart is alive and well in the guise of Allen Stone. The self-described “hippie with soul,” is a masterful young vocalist whose style comes from a time when Stax and Motown ruled the radio waves and the only way to listen to music was on vinyl. Stone got his start singing in his father’s church, but when he discovered Stevie Wonder, Marvin Gaye, Aretha Franklin and other classic soul/R&B artists of the 1960s and 70s, he found his true voice. On his second record, Allen Stone, the 26-year-old tackles social and political issues of the day and performs with Raphael Saadiq’s backing band. His voice is resoundingly mature for someone in his second decade and his fresh, energetic phrasing is a revelation.
