Tori Amos is an American singer-songwriter and pianist. She is a classically trained musician with a mezzo-soprano vocal range. Having already begun composing instrumental pieces on piano, Amos won a full scholarship to the Peabody Institute at Johns Hopkins University at the age of five, the youngest person ever to have been admitted. She was expelled at the age of 11 for what Rolling Stone described as "musical insubordination". Amos was the lead singer of the short-lived 1980s pop group Y Kant Tori Read before achieving her breakthrough as a solo artist in the early 1990s. Her songs focus on a broad range of topics, including sexuality, feminism, politics and religion.
