The beginnings of The Symphony Orchestra RTV Slovenia reach as far back as 1955 when it was conducted by the professor from the academy of music, the violin virtuoso and composer Uroš Prevoršek. The Orchestra was later conducted by Samo Hubad, Stanislav Macura, Anton Nanut and Lior Shambadal.
In September 2003 the chief conductor of the orchestra became David de Villiers; in Autumn 2006 the baton was taken over by the English conductor of the Chinese origin En Shao.

The orchestra performs an extensive and rich repertoire from baroque to modern symphony music, opera, oratorio and cantata, stage and film music, mostly with a stress on the creativity of Slovene music.
