Sarah Jarosz was 18 and doe-eyed when she released her debut album, just a few months before she also entered her first year at New England Conservatory. At the time, the rising singer-songwriter and mandolin player, who also holds her own on guitar and clawhammer banjo, seemed a little on the fence about the decision.
Four years later, Jarosz has recently graduated – not only from college but from Americana’s minor leagues. “Build Me Up From Bones,” her forthcoming third album for Sugar Hill Records, is the work of an artist who has developed considerably as a writer, singer, and multi-instrumentalist. She’ll celebrate its release with a show at the Sinclair in Cambridge on Sept. 14. Full story for BostonGlobe.com subscribers.
