“Falling Out Of Love” on Mary Gauthier’s 2005 release “Mercy Now” is the most haunting un-love song I've ever heard. It arrests me every time. She’s done plenty since, but hasn't lost any of her love-lost charm and tarnish. Gauthier sings of a life lived hard: abandoned at birth in the Big Easy, she ran away from her adopted home at 15, was in and out of rehab, stole a car and spent her 18th birthday in jail. She ran her own Cajun restaurant in Boston and didn’t write her first song until she was 35. That’s right. You can hear it all in her voice and on her brand new album, “Trouble & Love.” Captivating, haunting, and starkly beautiful.
