Hayley Westenra's voice is so smooth in this cd. All her notes are silky with gentle vibrato. It is the perfect background music for any situation. For the first two days after I bought it, I listened only to this cd. It is amazing to hear how her talent has progressed since her first cd. I bought the cd over holiday, and when I came back to college, I played in in my dormitory room, and all of the people who heard it, (even hard rock lovers) were amazed at the beauty of her voice, and love hearing the cd. She sings diverse styles, from the song she sang with the Celtic Women, Scarborough Fair, to Shenandoah, to Abide With Me. All carry with them her distinct Celtic sound, though. Hayley Westenra is definitely my favorite soprano. She has none of the annoying elements that many other sopranos have.
