The master of metamorphosis: that too is Josquin Desprez. In his masses he prefers working with existing material, by means of skilful cutting and pasting, literal quotation, or imaginative paraphrase. In the Missa Pange lingua, for example, the basic plainchant melody becomes like putty in Josquin’s expert hands. With this masterpiece, Pedro Teixeira and the Portuguese Officium Ensemble (one of the revelations of the England Festival edition in 2015) promise to deliver yet another exciting concert.
