The tenor Mitja Gregorac very successfully contributed his share to the performance of Missa Solemnis, bringing to it his beatiful voice and sound musicianship
Belgrade ("Borba", February 1963)
... Schon diese barocken Ariosi zeigten den Sänger als ausgezeichneten Tenor. Dass es aber auch gesangstechnisch weit Schwierigeres zu meistern wusste, bewies er in den Drei Liedern zur Harfe von Duparc, dessen stylistische Nähe zu Debussy deutlich ist, und in den sehr wort- und sinngezeugten sechs Hölderlin-Fragmenten op. 61 von Benjamin Britten.
Jochannes Frankfurter (Graz, Neue Zeit, Oktober 1968)
Particulary successful in Brittens wonderful cycle "Les Illumilations" was our tenor soloist Mitja Gregorac, the leading artist in this field in our country. He has both a highly cultured and accurate way of singing, and a very beautiful voice which never fails him.
("Nasi razgledi", Ljubljana 1963)
The tenor Mitja Gregorac - good in timbre, and best in interpretation.
