Annett Louisan is a German singer. She lives with a large part of her family in Hamburg. Louisan is her stage name, derived from the name of her grandmother, Louise. Concerning her birth year, there is contradicting testimony, with the official date being given as 1979. In 2004, she married Gazi Isikatli, a Turkish business student. Her first album, Bohème, has been listed on German charts for almost a year, with a peak ranking of third place. She appeared on the AVO Session program at Basle on November 7, 2006.

Annett Louisan does play a wide variety of music with blues, soul, jazz and swing. The lyrics of her songs are mostly about love, failure and disappointment. Annett Louisan is one of the few German artists who have obtained a high profile with chanson-style songs. Apart from Louisan's own musical interpretation, this is due to the lyrics of her producer, Frank Ramond, as well as the compositions of her songwriters, Hardy Kayser and Matthias Hass. Her lyrics also deal with the politicized issues of female self-conception and societal roles, creating a complex ambivalence. This became most apparent with her first single Das Spiel. In this song, roles with contrary approaches to sexuality and inter-personal relationships (i.e. the child, the woman and the emancipated) are combined. Musically, her second album moves away from pop and concentrates more on the French-German chanson-tradition. Bal-musette, Tango and Bossa Nova-rhythms give the songs diversity. Unobtrusive backings allow the often breathy voice of Louisan to remain prominent.
