In 1999 she recorded her first solo album, Kasia Stankiewicz, with soul and jazz compositions.[3] In 2001 Kasia Stankiewicz recorded "The Bridge Song" with the German electronic music group Tangerine Dream. The single promoted their new album around the world. In 2003 she produced and published a new album called Extrapop. The first single "Schyłek lata" (The End of Summer) was a smash hit in Poland, and two other singles "Francuzeczka" (The French Girl)and "Saint Etienne" were successful too. Kasia has definitely left behind a "good girl" image.
