On her striking debut, the conservatory-trained singer declaims over melodies that stop and start with her every syllable, then waft around her like a pleasant daydream. She approaches music with the swing of a jazz singer, the heft of a soul performer, and the tonic clarity of a classical vocalist. She combines those impulses on sunny pop gems like “Like the Morning Dew,” while “Green Garden” bubbles with handclap percussion and light xylophone melodies. The full orchestra that backs many of these tracks serves to heighten her infectious sense of wonder.
