This eighth and final volume of Naxos’s acclaimed survey of Haydn’s Masses contrasts the intimately scaled Little Organ Mass with the symphonically conceived Mass in B flat major, nicknamed Theresienmesse after Marie Therese (wife of Emperor Francis II and soprano soloist in the first performances of The Creation (8.557380–81) and The Seasons (8.557600–01)). The Great Organ Mass is available on 8.572125 as well as in the 8-CD boxed set of the Complete Haydn Masses (8.508009): ‘Bravo!’ (Early Music America); ‘…monumental recording…the first-ever collection of the complete Haydn Masses performed on period instruments.’ (Baker & Taylor CD Hotlist)
