Some artists find their voice by conquering their fears. Annie Clark turns hers into nervous -- and nervy -- pop songs. When Annie Clark was ten years old, she had her first panic attack. She was at a Texas Rangers game, not far from the Dallas suburb where she grew up. Around the second inning, she caught a glimpse of the sky where it met the end of the stadium bleachers, like a horizon line. "I remember looking at the sky and thinking that the universe is so big and it's all chaos," she tells me 18 years later on a hot July afternoon in downtown Manhattan. "I call it 'the dark fear.' At any moment, the dark fear could come in." She still gets panic attacks, but not as often, and the stimuli that provoke them needn't be as ponderous as realizing the world is enormous and you are inconsequential.
