Requiem (Weinberg)

Mieczysław Weinberg composed his Requiem Op. 96 between 1965 and 1967. Like other Soviet Requiems such as Dmitri Kabalevsky's it does not set to music the Roman Rite liturgy, but secular poems by Mikhail Dudin, Munetoshi Fukugawa, Federico García Lorca, Dmitri Kedrin and Sara Teasdale. The use of anti-war texts links this work to Benjamin Britten's War Requiem, which Weinberg knew well. 
It consists of the following movements:
It wasn't performed in the composer's lifetime, the premiere only taking place on November 21, 2009 in Liverpool by the Royal Liverpool Philharmonic Orchestra and Chorus, with Thomas Sanderling conducting the ensemble. 
The Requiem was published by Peermusic's Hamburg branch in 2007. Their description page (and the NUKAT description) note that the work requires soprano, children's chorus, mixed chorus, and full orchestra.
