Iris DeMent's pure storytelling and powerful, trembling soprano first floored listeners on her 1992 debut "Infamous Angel," a collection of introspective songs about faith, loss and love (gone good and bad). Her stunning follow-up a year later, "My Life," had even more ache and polish, but retained a folky guitar/standup bass/piano soundscape. She toughened things up on "The Way I Should," adding a rocking sound and cutting social issue-based protest songs like "Wasteland of the Free." In 2004 she released "Lifeline," an album of traditional gospel songs. She will close out a 16-year gap since her last album of originals on October 2, 2012 when "Sing the Delta" is released on the acclaimed folk singer's Flariella label.
