Rural Bernville, PA’s Priscilla Ahn has grown up into quite a sophisticated artist. Her second album, When I Grow Up, is a confident collection of songs from a young woman who has the ability to hold a room with a gentle, reflective folk song like “One Day I Will Do,” where her acoustic guitar and modest orchestration give her music the sound of a classic mid-‘60s folk album. The title track is a bit of an upmarket production, with some brilliant keyboard figures swirling around Ahn’s look at childhood. But mostly producer Ethan Johns keeps things fairly organic. She does a sultry cover of former collaborator Benji Hughes’ “Vibe So Hot.” “City Lights (Pretty Lights),” co-written with Inara George, slips towards a beautiful music-box Parisian sorrow. “I Don’t Have Time to Be In Love,” a duet with co-writer Charlie Wadhams, has a storybook feel. “I Will Get Over You” has a bright early-‘70s AM radio sound. But Ahn can still strip it down for intimacy’s sake as she does on the many ballads placed throughout the album.
