In 2001 she was the "high soprano" in music of Luigi Nono, in a concert performance in the "Zeitfluss" series at the Salzburg Festival of his Io, Frammento da Prometeo for three sopranos, small chorus, bass flute, contrabass clarinet and live electronics that took place at the Kollegienkirche, Salzburg. The performance was recorded and released in 2004, at which time a reviewer wrote: "The singers are astonishing in their accuracy and tuning in these fiendishly difficult harmonies. Especially marvellous is the coloratura soprano Katia Plaschka." John Story commented in Fanfare: The recording was awarded the 2004 Preis der deutschen Schallplattenkritik in the choral works category. Plaschka has been a soprano with the Wiener Taschenoper in Vienna, which specializes in contemporary opera. In 2003 she appeared in the premiere of Wolfgang Mitterer's opera massacre, performed as part of the Wiener Festwochen, directed by Joachim Schlömer and conducted by Peter Rundel. In 2004 she was the singer for Mitterer's performance with dancers, Labyrinth for soprano and electronics, at the Semper Depot in Vienna, with choreographer Saskia Hölbling and her group DANS.KIAS.
