The present recording constitutes more than just a new version of the Vespers. It is the first recording of the Vespers in the alternative version proposed by the composer, without concertato instruments. It reveals the underlying matrix of the work we all know, the ‘original version’ to which Monteverdi added concertato instruments for use in large-scale performances. Respecting the structure of the Office of Vespers, Ludus Modalis has chosen to frame the psalms with the antiphons corresponding to a Marian ceremony. The interpretation proposed here is one influenced by the Renaissance tradition. It places the work in perspective in a musical world at the point of equilibrium between prima and seconda prattica, between the achievements of tradition and the contributions of modernity. © Alpha/Outhere
