Neko Case's lengthy career has shown how she can take her expressive voice into just about any genre, and it always electrifies. Her work with The New Pornographers on the bouncy indie-pop number “Letter from an Occupant” shows how she excels at high-energy melodies, while the low-key “Ragtime” brings things down to a near-whisper. The sultry Americana of “If You Knew” provides an open space that she fills with her gigantic voice.
