Blessed with a beautifully expressive, strident soul voice, Switzerland's Stefanie Heinzmann was always going to make waves. Her 2008 victory on a German TV talent show paved the way for a series of bold, funky pop songs that take the energy and confidence of ‘60s soul, the projection of rock and the breezy swagger of swing, underpinning them with a solid pop production. Heinzmann can most often be found either singing a protective shell around her beloved or flaying a foolish ex with the sharp edge of her tongue.
