Query: That voice!

This is a gorgeous album, and its so wonderful to hear that voice again after too long a wait. Jennifer can sing any style convincingly, but the ballads are the best. Her voice sails and soars, then drops to a hearbreaking whisper. She has one of the most textured and nuanced voices in the business, and this album is the perfect showcase for it.
