Franz Liszt was a pioneering 19th century Hungarian composer and pianist who was taught composition by Antonio Salieri in his early years. While Liszt composed religious works and helped other artists, some of his compositions used unprecedented emotional and psychological impacts with brutal sounds that may have planted the seeds for later heavy metal styles. Liszt felt free to portray all human experiences through his music, including the darker and more evil sides of life, though he was a devout Catholic not seeking to worship evil.
