KT Tunstall/Maddie Ross

Singer K.T. Tunstall, who started playing piano when she was only 4, launched her career with 2004’s Eye to the Telescope, an album that became a hit after she re-released it with “Black Horse and the Cherry Tree,” a tune that wasn’t actually on the initial pressing. Then, she had an even bigger hit with “Suddenly I See,” a track that was used in The Devil Wears Prada. Hillary Clinton even used the track in 2008 as part of her presidential campaign. Relentless touring and recording followed until Tunstall hit the wall a few years ago. She went to the Sundance Film Institute Film Music Program and learned to write music for soundtracks. Invigorated, she returned to the studio three years ago to cut KIN, an album of “big pop songs.” The second part of that trilogy, last year's WAX, is another solid effort. One album highlight, “The River,” starts as a pretty pop number with percolating synths and falsetto vocals. It eventually builds as Tunstall adopts a bluesy wail, and the guitars and drums kick in. Expect to hear it along with a mix of old and new songs at tonight's show. (Niesel)
