This vocal master-work from Vivaldi is less than a decade short of its 300th birthday but here comes up fresh and sparkling, and with the zest of a teenager. Vivaldi, who we know best as an instrumental composer, claimed to have composed some 90 operas, but few are heard today. This work is even rarer.

The liner notes tell us that as well as the operas, he wrote four oratorios. But Juditha Triumphans, based on a particularly blood-thirsty Biblical tale and described as a ‘sacred military oratorio’, is the only work to have come down to us. Judged by this sole work, the loss is ours. For the work is endlessly inventive, with some passages propelled by energetic momentum, and others paced like some peaceful inner reflection that ebbs and flows like our thoughts.

The choral singing and the orchestral playing of Cantillation and the Orchestra of the Antipodes manage to combine forthright appeal with fragile delicacy when needed. And the five vocalists are beautifully matched, with contralto Sally-Anne Russell particularly affecting in the title role. The oratorio for the most part has survived, but its overture has been lost. In its place, the Orchestra of the Antipodes performs a very effective concerto by Vivaldi with appropriately military-sounding timpanis and horns. It’s a convincing substitute, to usher in such a rare treat.

The live recording is both immediate and warm, with a tremendously realistic acoustic. Pinchgut Opera has been well served by its recordings and this is as good as it gets.
