Adrianna Rusowicz (8 September 1944 â 1 January 1991), known professionally as Ada Rusowicz, was a Polish singer, the vocalist of the band Niebiesko-Czarni.
Rusowicz was born on 8 September 1944 in Vilnius, but spent her childhood in Dzierzgoà Â. In 1962 she graduated from high school in the School Complex in Sztum. Then, in Olsztyn, she started teaching as a teacher, at the same time she became interested in music and started working with student music groups. In 1963, she won a distinction at the 2nd Festival of Young Talents in Szczecin, and the following year she auditioned for Czesà Âaw Niemen's choir Bà ÂÃÂkitne Poà Âczochy (or Blue Stockings), which accompanied the band Niebiesko-Czarni.
In 1968, Rusowicz won the title of the most popular singer of the year. In the years 1968âÂÂ1970, together with Niebiesko-Czarni, she gave concerts in France, Belgium, Yugoslavia, Finland and West Germany. She performed with the ensemble until its dissolution in 1976, and from 1967 she was their soloist. Then she performed with Wojciech Korda in the duo Ada i Korda, but the band was not successful. In 1980, she retired from stage work and devoted several years to family life.
During the period of cooperation with Bà ÂÃÂkitne Poà Âczochy, Rusowicz started an affair with Czesà Âaw Niemen. Her husband was a guitarist from the band Wojciech Korda, with whom she had two children: Bartà Âomiej (born 1977) and Anna (born 1983).
On 1 January 1991, Rusowicz returned with her husband and newly met friends from a concert in Warsaw. She was killed as a result of a car accident near Poznaà Â; only Korda survived. She was buried at the Mià Âostowo Cemetery in Poznaà Â.
In 2012 in Dzierzgoà Â, in the City Park, a concert hall was named after Rusowicz and a plaque commemorating the singer was unveiled.
By a resolution adopted at the session of the Poznaà  City Council on 12 July 2016, the square located between Bolesà Âawa Krzywoustego, Pleszewska, Brneà Âska and Anna Jantar streets near the "Posnania" shopping center in the area of the Rataje estate in Poznaà  was named after Ada Rusowicz.
