The Prague Radio Symphony Orchestra (Symfonický orchestr ÃÂeského rozhlasu, Czech acronym SOÃÂR, English acronym PRSO) is a Czech broadcast orchestra based in Prague, the Czech Republic. The SOÃÂR performs concerts at the Dvoà Âák Hall of the Rudolfinum, at the Forum KarlÃÂn and the Convent of Saint Agnes in Prague, as well as Studio 1 of Czech Radio in Prague.
The precursor ensemble of the SOÃÂR was the Radiojournal Orchestra, which gave its first concert on 1 October 1926 under Joà ¾ka Charvát, the first chief conductor of the orchestra. By 1952, the popularity and size of the Radiojournal Orchestra was such that a second orchestra, the Prague Radio Symphony Orchestra, was split off from the Radiojournal Orchestra. By 1964, two separate orchestras were affiliated with Prague Radio, the Prague Radio Orchestra and the Prague Radio Symphony Orchestra. These orchestras subsequently combined to form the present orchestra.
From 2018 to 2022, Alexander Liebreich was chief conductor and artistic director of the SOÃÂR / PRSO. In May 2021, the SOÃÂR / PRSO announced the appointment of Petr Popelka as its next chief conductor, effective with the 2022âÂÂ2023 season. The current principal guest conductor of the SOÃÂR is Marek à  edivý. In May 2021, the SOÃÂR / PRSO announced the appointment of Robert Jindra as its next principal guest conductor, effective with the 2022-2023 season. Popelka is scheduled to conclude his tenure with the Prague Radio Symphony Orchestra at the close of the 2025-2026 season. In September 2025, the SOÃÂR / PRSO announced the appointment of Elias Grandy as its next chief conductor, effective with the 2026-2027 season.
The SOÃÂR / PRSO is a featured orchestra at such festivals as the Prague Spring International Music Festival, Dvoà Âák Prague International Music Festival, Smetana's Litomyà ¡l, JanáÃÂek Music Festival, or International Music Festival ÃÂeský Krumlov. The orchestra's discography includes the first set of complete recordings of Miloslav KabeláÃÂ's eight symphonies (Supraphon, 2016).
