Patty Griffin has always had a gift for locating a song's nerve endings; for surveying her subject matter and identifying the most efficient possible pathways to listeners' emotions. Her warm, wise voice is comforting, inviting and relatable, even — perhaps especially — as she tackles weighty subjects like middle age and the death of a parent. The memory of Griffin's father hangs over her recent seventh album, American Kid, but the singer remains far too resourceful to make it a collection of navel-gazing dirges about mortality. In sampling a few of the record's many highlights at the NPR Music offices, she takes care to balance the exquisite mourning of "Favorite Son" — and the sweetly somber "That Kind of Lonely," which Griffin describes as "a song about finally letting go of your delayed adolescence" — by closing her set with the playfully bawdy, kindly celebratory "Get Ready Marie." Inspired by a favorite photo of her grandparents, the song finds Griffin viewing two complicated lives with the generous, hopeful eye she's been casting on her subjects for three fruitful decades now.
