This Portland, Ore., quartet plays light, retro, coffee-shop jazz pop—a perfect fit for the Norah Jones era we inhabit. Subtle, yet substantial, singer Teisha Helgerson interprets the songs of guitarist Scott Weddle and bassist Jesse Emerson with gentle elegance. Resolute on “Better Than Sleeping Alone,” the spare arrangement provides just the right support. A walking bass line and drum shuffle carries the listener forward, while bluesy guitar creates less-certain psychic space.
