THE singer-songwriter Tori Amos has left Epic Records after six years to become independent and urged her fellow artists to "stop being dependent, dependent on any system that has become undependable. In a statement on her Web site (toriamos.com), Ms. Amos, 44, said she looked forward to crossing into the new uncharted music frontier. She released three albums on Epic, most recently "American Doll Posse" in 2007, which hit No. 5 on the Billboard 500. Before that she was with Atlantic from 1992 to 2001, when she, along with Rod Stewart, Poe, Collective Soul and other artists, left that label. More Articles in Arts " - New York Times
