On the occasion of the composer’s 75th birthday on 16 December 2007, WERGO continues publishing CDs within the Edition Rodion Shchedrin with a world premiere recording. The Russian choral opera “Boyarina Morozova” describes the schism in the Russian Orthodox Church that began in the seventeenth century. This religious conflict, whose effects are still felt today, ignited in reaction to the ecclesiastical reforms of Nikon, then patriarch of Moscow.

The composer's preface: "Setting to music this terrible page in the history of the schism of the church and the rise of the Old Believers in Russia and the bitter fates of the people involved was a long-held dream. Several times I began it, but each time I dropped it again, because I could not, it seemed to me, suitably tackle this gripping theme. Only when it became clear to me that it should take the musical form of a 'Russian choral opera' did my work make progress. As literary materials I used texts from the two great books 'The Life of Protopope Avvakum, Written by Himself', and 'The Life of Boyarina Morozova, Princess Urusova, and Mariya Danilova'. The four soloists (Boyarina Morozova; her sister, Princess Urusova; Protopope Avvakum, and Czar Alexei Mikhailovich) would be joined by three instrumental soloists: trumpet, timpani, and a percussionist playing other instruments. The choir would not only take on the usual role of a choir but that of the orchestra, which sometimes plays the part of a narrator, sometimes that of a modest accompanist."
