Like Patty Griffin, Smith is a deft songwriter straddling folk, country, and pop, with a lovely girl-woman soprano that feels like cotton sheeting after a bath. Long Island Shores is twangier than her 2004 debut, partly due to guitarist/Emmylou Harris cohort Buddy Miller. And once again, the former seminary student brings unforced spirituality into lean songs about love, home, and heartbreak. They could be megahits for heavier-handed singers. But her eddying flow is made for more intimate spaces than supermarkets; if her success is modest, her talent isn’t.
