Anna Madison was born in Rio de Janeiro. Having Swedish/Brazilian roots, she moved to Stockholm at the age of 10 where she learned to play the guitar.

From being a dancer (jazz and ballet), Anna M shifted musical interests to playing instruments and composing; first compositions date to the age of 13. At first she performed with her guitar on improvised stages (pubs, the streets...) but soon had the opportunity to engage in larger productions, including musicals, concerts, plays, dance shows, hosting events, etc.

After living in Brazil, Sweden, and California, her home became Paris. Anna M began singing with various groups, including the rock group formerly known as Reevox. She then started her long time collaboration with Frisco (headed by composer/actor Vincent Martinez) as their lead singer. The group launched Anna M with an album of 12 songs, and her first video of the track "Be A Man", introducing an pop/electro-funk style.

Anna M has since then composed songs with Sony music, and EMI (composer Vinch), and is now signed by the music publisher Kendell Entertainment. Other groups that Anna M worked with are Ocean Drive, Boulawan, Astroboyz (Sony), Bustafunk (Universal Publishing), Iccops, DJ Laurent Schark, Laurent Konrad (Discobitch, Helmut Fritz), Mike Organiz, Lone Lebone, and others. She has also lent her vocals and composing talents to French rap artist Sokrate, featuring the English/French track "Out of Control/Hors Control."

In 2012, Anna M interpreted Drusilla in the musical " Pop'pea " at the Theatre du Chatelet in Paris, alongside Benjamin Biolay, Carl Barat, Marc Almond, Fredrika Stahl, among others. This was a video-pop version of the opera of Monteverdi.

In 2013, Anna M spent a year in Rio de Janeiro working with producer Eugenio Dale and performing. She currently lives between Stockholm and Miami.
