Korovessi studied from 1970-1975 at the Athens School of Fine Arts under various sculptors including Dimitri Kalamara.
1985 marks an important turning point in her work where she became specifically interested in the sound analysis of words, leading to her research at the Centre of Electronic Music founded by Iannis Xenakis.
Korovessi begun to create works that show the use of technology, music and science, resulting eventually in the ‘sound – sculptures’ which were later called SonArt.
In 1988, Korovessi was awarded by the Municipality of Athens, ‘Work of Communication‘ through a public commission and creates the sound sculpture,’Communication’ (Messogeion Avenue, Athens).
The Inmovements exhibition of 1993, the artist’s first solo show (Epoches gallery), was another turning point for the artist, exhibiting works made of wood, metal and stone.
In 1994 Korovessi represented Greece in the 4th Sculpture Triennale, France and 1997 saw the artist again awarded for her work and makes the National Resistance Monument, located at Karakolithos, Boeotia.
