This is the second album pairing Alfred Schnittke and Arvo Pärt from the Estonian Philharmonic Chamber Choir. The first, released in 2018, brought the group a Gramophone Award, and the BIS label and conductor Kaspars Putniņš have apparently decided to stick with what works. Both albums are superb. Schnittke and Pärt haven't often appeared together on recordings, Schnittke's stylistically allusive language being miles away from Pärt's minimalism, a fine example of which is provided by the Seven Magnificat Antiphons heard here.

Less well known among his works, the Missa sacra, Op. 147, bears witness to Robert Schumann’s late interest in sacred music – and in particular in Catholic church music. The work would have a rather difficult fate: during Schumann’s lifetime, it was neither published nor performed in its entirety. Even after its posthumous première, opinions were lukewarm. Wrongly so: the Missa sacra is a fascinating attempt to update sacred music through a refined post-classical musical language. It was originally conceived for orchestra, but Schumann also made a version for organ, presented here. This version allows great vocal transparency and immediacy, thus contributing to a clearer vision of the work.

The music of the Russian Orthodox Church was an essential part of Sergei Rachmaninov’s musical background. As a boy he was deeply moved by the sound of St Petersburg’s cathedral choirs, and phrases reminiscent of liturgical chant permeate his music. His Vespers has long been admired as a summit of Russian liturgical music. It has unfortunately tended to overshadow the Liturgy of St John Chrysostom, his earlier large-scale sacred composition. Named after the fourth-century Archbishop of Constantinople and Church Father, the Liturgy consists of a sequence of prayers, psalms and hymns, which are sung or chanted by the different participants in the service.

As Alfred Schnittke and Arvo Pärt both adopted the Orthodox faith in the 1970s, Orthodox choral traditions became increasingly prominent in their work, but both composers also looked to the music of the Western church. Schnittke’s Three Sacred Hymns set three prayers, familiar in the West as Ave Maria, the Jesus Prayer and the Lord’s Prayer, and evoke Orthodox chant. His Choir Concerto, on the other hand, draws on Russian choral music of the 19th century and the tradition of large-scale concert works based on Orthodox choral music. The texts by the medieval Armenian poet Gregory of Narek are informed by a humanistic individualism, with the poet directly expressing his emotions and often writing in the first person.
