With representatives of six other former Eastern bloc nations and nations of former Yugoslavia, Sillamaa performed "Muretut meelt ja südametuld" at the Kvalifikacija za Millstreet semi-final round broadcast live on 3 April 1993 in Ljubljana, when four of the seven competing entrants were eliminated, including "Muretut meelt ja südametuld" which finished the round at #5.

In 1992 Sillamaa played her first adult role in a stage musical: Mary Magdalene Jesus Christ Superstar at the Linnahall.

In 2000 Sillamaa commenced studies at the Higher Drama School of Estonia intending to complete a four-year programme in stage directing.
