Oxford’s renowned early-music consort Contrapunctus brings to life masterworks of the rich Portuguese musical tradition of the sixteenth and seventeenth centuries. At the heart of the programme is Duarte Lobo’s Missa de beata virgine, a masterpiece from the chapelmaster of Lisbon Cathedral. Alongside it are motets by Manuel Leitão de Aviles—an intriguing figure who worked in Granada—uncovered by the ensemble’s director, Owen Rees.
