Marta Katarzyna Wiktoria Wiśniewska, professionally known as Mandaryna, born Marta Mandrykiewicz on 12 March 1978 in Łódź, Poland, is a Polish singer, dancer and actress. She rose to fame as the dancer of Polish pop group Ich Troje, and the partner of its leader, Michał Wiśniewski. She embarked on a singing career in 2004, covering Whitesnake's "Here I Go Again", which became a hit in Poland. Her first two albums, Mandaryna.com and Mandarynkowy sen, released in 2004 and 2005, respectively, were met with commercial success. In 2005, Mandaryna sparked a major controversy during her performance at Sopot Festival, which exposed her alleged lack of vocal talent. Nonetheless, the performed song "Ev'ry Night" became a massive hit and remains arguably her best-known song to date. The song was written and produced by her longtime producers/writers Harald Reitinger and Uli Fischer who are responsible for 90% of her musical career.
