The special importance of psalm settings within the church music of Antonio Vivaldi is explained by the dominant position of psalms in the Vespers liturgy and by the important role which Vespers played in the sphere of church music. ‘In due cori’ indicates a composition for two ensembles, each with its own set of soloists, choir and orchestra. The performers on this outstanding recording are the Estonian Philharmonic Chamber Choir and the Talinn Chamber Orchestra, conducted by Tonu Kaljuste.
