Jordi Savall presents the world premiere recording of a new performing edition of Mozart’s unfinished “Great” Mass in C minor, K. 427, restored and completed with historical rigor and musical sensitivity. Basing their score on Mozart’s own compositions and sketches, Savall and his fellow conductor/musicologist colleague Luca Gugliemi have fashioned a new version that The Times says “goes some way towards turning the torso into a roughly Mozartian whole.” Sopranos Giulia Bolcato and Elionor Martínez, tenor David Fischer, and bass-baritone Matthias Winckhler are the stylish soloists with Bolcato gaining two additional featured solos in the completed Credo and the new Agnus Dei sections. The singers of La Capella Nacional de Catalunya and the period instrumentalists of Le Concert des Nations turn in their customary responsiveness and virtuosity for maestro Savall.
