Her voice is used immensly to reach the highest and lowest notes, 'Butterfly' and 'The Roof' are my favourites. This album is of her leaving her husband and a butterfly (herself) emerging and flying off and finding a new life! The words are heart warming and i can easily get lost in the album. I have been listening to this album at night, during the day and i will never tire from this album. Well done on a great album!!!
