She first gained international attention by winning the first prize at the Benson and Hedges International Voice Competition in London, which was followed by winning second prize at the International Vocal Competition in Rio de Janeiro. Early on she got a long-term contract with The Grand Theatre in her home town Poznań to which she was closely linked from 1984 to 1998. Already in January 1986 her international career started and she debuted as Liù at the Royal Opera House, Covent Garden, and thereafter sung at the most prestigious opera houses of Europa and America.

In the United States she earned high acclaim as Sandrina in Mozart's La finta giardiniera at the Brooklyn Academy of Music, as Donna Elvira at the Los Angeles Opera and as Alice Ford in a concert version with the Minnesota Orchestra under Jeffrey Tate. At the Atlanta Opera she stunned public and press in the title role of Puccini's Madama Butterfly.

In 1992 she interpreted successfully the role of Sandrina in La finta giardiniera at the Salzburg Festival, directed by Ursel and Karl-Ernst Herrmann. A long-term commitment bound the singer also to Oper Zürich in Switzerland where she was seen and heard as Ariadne, Emma, Lisa, Mimi and Tamara as well as in four leading Verdi-roles, the two Leonoras, as Elvira in Ernani and Elisabetta in Don Carlos.

She also sung the soprano parts in Mozart's Requiem, Poulenc's Gloria and Britten's War Requiem.
