It's easy to get the wrong impression about Scottish singer-songwriter KT Tunstall if you've only heard her bare-bones single "Black Horse and the Cherry Tree" perhaps that she's a granola folkie, or a neo-blueswoman like Joss Stone. But it turns out that "Tree" isn't even the best song on her debut, Eye to the Telescope, a diverse album whose songs range from rich, soaring dream-pop ("Other Side of the World") to PJ Harvey-sassy struts ("Another Place to Fall"). "The material that's on [Eye], it suits the mellower approach to sit and listen to it in your living room," Tunstall explains from a Philadelphia hotel room. "But when it comes to playing the stuff live, there's four guys in the band. We pretty much rip it up and start again, really. I don't really subscribe to the idea that the songs are the way they are on the record, and that's it. They constantly turn into new things."
