Two legends of the 20th century international music scene, Yehudi Menuhin and Nadia Boulanger, provided Marina with the ticket into a bright future. The latter stated that Marina "professes her art with striking conviction", whereas the great violinist believed her to be "a person of warmth and charm, who would be an asset to the musical life of any community".
The life path of Marina Horak was marked by diversity throughout: harpsichord and contemporary music, chamber music and piano duo, solo performances and accompanying singers, teaching and writing articles, lecturing and organizing concerts, poetry and translating. In the Eighties she researched and wrote an extensive report on the situation of young musicians in Europe for the Commission of the European Community, and she even took up the challenge of appearing on the stage of the Celje City Theatre, playing keyboard one in the musical Chicago. In November 2000 she was elected Donator of the Year for her charity work with refugees by the "Naša žena" magazine's initiative People with open hands.
In December 2008 she was awarded the Betetto-Prize for outstanding artistic achievements by the Slovenian Society of Music Artists. Peter Feuchtwanger, the mentor of world renown, wrote in May 2000 after Marina\'s concert in London: "Slovenia can be proud of such a sublime artist", and this is how composer Pavle Merku experienced her concert in Trieste in May 2005: "The emotion that Marina transmits in her interpretations is an active force, which has nothing in common with the passive force of lyrical sentimentality. Therefore I consider her a great artist."
At the Academy of Music in Ljubljana her pedagogical dreams came to fruition: she created the elective subject Dimensions of Performance, in which she uses her own specific approach to guide young people towards a better understanding of themselves and a deeper, genuine musical expression.
