This is a clip from the song "On our way" and it's from the "Back to Basics" album.This is one of my favourite vocal runs that she has sung in her chest voice. It showcases her brilliant technique as she moves up and down the scales with ease and finesse. :
This song is also from the "Back to Basics" album and is called "Without you". I love how she applies her trademark runs within her head voice creating a warm inviting sound.
