The first thing you need to know about dance-pop ingenue Charlotte Sometimes: That's not her real name. The artist formerly known as Jessica Charlotte Poland took her stage name from her favorite children's book, the Penelope Farmer story of a young, time-traveling boarding school student. The second thing you need to know: The young singer-songwriter has been performing music since childhood, playing the guitar since she was 14 and releasing EPs (and one live album!) in high school. The third: This particular singer-songwriter is full of surprises. Case in point? The first, rather dark single off her debut EP for Geffen, Waves & the Both of Us, is called "How I Could Just Kill a Man." It was inspired by a Cypress Hill song of the same name and a terrible breakup from her ex-boyfriend. Oh, and in the video, she "kills" the dude playing him in four different ways.
