Thanks to Terry Gross of NPR, whose program Fresh Air reminded me of the Harlem-based Addicts Rehabilitation Choir. Directed by former heroin addict James Allen, this is a gospel choir with a passionate repertoire of inspirational hymns appealing to anyone recovering from anything. Every singer in the group was once addicted to drugs or alcohol. Here’s where to learn more about their work, listen to their music , and buy their CDs and tapes.
