30, is a radio opera in one act by composer Franz Reizenstein.
The work uses an English language libretto by Christopher Hassall to tell the tragic tale of a German woman who is forced to leave her country due to oppression from the Nazi regime, as the Nazis did not like her political views.
[1] The opera was commissioned by the British Broadcasting Corporation following the popular success of Reizenstein's 1951 cantata Voices of Night.
[2] The opera premiered on 25 July 1952 on BBC Third Programme with conductor Norman Del Mar leading the BBC Symphony Orchestra and singers Victoria Sladen (as Anna) and Lloyd Strauss-Smith (as Pavel).
[4] The Annual Register wrote that the opera "suffered from the composer's emotion being too closely engaged in the sufferings of the heroine, a refugee from political oppression".
