The Munich Radio Orchestra (German: Münchner Rundfunkorchester) is a German symphony orchestra based in Munich. It is one of the two orchestras affiliated with the Bavarian Radio (Bayerischer Rundfunk), the other being the Bavarian Radio Symphony Orchestra. A precursor ensemble to the Munich Radio Orchestra was established in the 1920's. The current Munich Radio Orchestra was formalised in 1952, with Werner Schmidt-Boelke as its first chief conductor. The orchestra's focus has historically been on light music, with particular emphasis in its early years as an orchestra for operettas.
