Within the field of anime, Ann Lewis is recognized for her contributions to the soundtrack of the television series Jungle no Ouja Taa-chan, also known as Jungle King Taa-chan, which aired from 1993 to 1994. For this series, she performed two of the ending theme songs. The first ending theme, used for episodes 1 through 26, is titled VIRGIN LAND.

Lewis is noted for her distinctive husky vocal style and her ability to blend Western rock influences with Japanese kayoukyoku pop traditions, a fusion that helped her stand out in the Japanese music industry during the height of her career. Her bold fashion sense and energetic stage presence made her a trendsetter and an influence on subsequent generations of Japanese rock artists. In 1995, she began to suffer from chronic panic attacks, which led her to semi-retire from the entertainment industry. She subsequently relocated to Los Angeles, California. In the 2000s, she made sporadic returns to music, releasing several self-cover albums including Rebirth Self-cover Best in 2005. Following her music career, Lewis has been active as a creative director and designer, working on interior design projects, jewelry design, and other creative ventures.
