Who is KT Tunstall

KT Tunstall  is a Scottish singer and songwriter.

Although her first name is Kate, she chooses to go by KT as her first name, saying "Kate just makes me think of a buxom lass baking bread for her man working in the fields. I have no problem with that, but it's just not really how I pictured being a rock star." Also, Tunstall spells her first name KT (as opposed to Katie) to differentiate herself from fellow singer Katie Melua.
