DHM was brave to record Gluck´s version of La Clemenza di Tito, perhaps it´s the company´s birthday present for the 300 year old composer. And I say brave, because it´s very long, almost 4 hours long, and comes in 4 cds, though DHM is selling it at the price of 2.
Imperial Court Poet Pietro Metastasio wrote la Clemenza di Tito originally for Antonio Caldara, and since then dozens of composers have used the libretto, Johann Adolf Hasse set it not once but twice, and most famously it was Mozart´s last opera.
It would be silly to compare Mozart´s version to Gluck´s because there are vast differences between them. Gluck´s still belongs to his pre-reform period, so it still dutifully obeys all opera seria strictures: long, elaborate arias that serve the singers well (1752 was still the heyday of the castrato). Mozart had already moved on and made Caterino Mazzolá, to add concertante numbers that the original libretto didn´t have to push forward the action. It´s funny, but we could say that Gluck´s is early Gluck, while Mozart´s is late Mozart, though Gluck (39) was actually older than Mozart (35) when he composed his version.
The enterprise is worthwhile, it was recorded live in November of last year in concert form, it´s as quiet as a studio recording. All the singers are very good, especially Raffaella Milanesi who sings Sesto and Laura Aikin who sings Vitellia. Werner Ehrhardt former first violin of Concerto Köln, has made L´ Arte del Mondo a truly splendid band. So, it´s enjoyable, but as long as Lohengrin.
