Demofoonte dates from the early Milan years of Christoph Willibald Gluck (1714-1787), long before the radical reform operas for which he is most famous and his break with opera seria and the librettos of Pietro Metastasio. Gluck arrived in the northern Italian city in 1737 and was mentored there by composer Giovanni Battista Sammartini. Though Sammartini primarily composed symphonies and music for the church, Milan boasted a vibrant opera scene, and Gluck soon formed an association with one of the city's up-and-coming opera houses, the Teatro Regio Ducal.

This is the 45th title in the Vivaldi Edition, 3 years after the first recording dedicated to Vivaldi scores discovered in Europe between 2000 and 2007, now in its 12th year. This second volume features the most recent discoveries in world premiere recordings and will further contribute to complete one of the most fascinating jigsaw puzzles in musical history Federico Maria Sardelli is a member of the musicological committee of the Istituto Italiano Antonio Vivaldi at the Fondazione Cini in Venice, for which he has published numerous scholarly essays. In July 2007 Peter Ryom chose him to continue his monumental work of cataloguing the music of Antonio Vivaldi; since then, Sardelli has been the editor of the Vivaldi Werkverzeichnis (RV).

While it isn't Handel's most obscure opera (hum a few bars from Catone, anyone?), Siroe, Re di Persia is definitely on the margins. It's hard to say why exactly, although the unflatteringly edited Metastasio libretto (by Nicola Haym) is surely part of the reason; the character and conflict development of the original are largely missing from the version Handel set. But the music is Handel at his best, and let's face it: from the perspective of a modern listener, plot is not the main draw of opera seria. With that in mind, Harmonia Mundi's complete recording, with Andreas Spering and the Cappella Coloniensis, is an excellent first step toward giving Siroe wider exposure. It's well played, thoughtfully conducted, and it features an excellent trio of leading ladies.

Gluck wrote his opera seria Ezio in 1750 for production in Prague. (In 1762, after the formal and stylistic breakthroughs of Orfeo ed Euridice, he revised the opera for a Vienna production, but it's the original version that's recorded here.) The opera has many of the characteristics of Italian late Baroque opera; it's essentially a series of arias separated by accompanied recitatives, the formula that the composer reacted against in Orfeo. It's not Gluck at his most innovative or original, but it's a fine example of opera seria, with a number of impressive arias and some very expressive recitatives, and it can make quite an impact in a performance as fine as this one.

Handel's opera recorded live at the Semperoper, Dresden, in June 2000. Equal parts comedy, tragedy and romance, the story revolves around the love both Xerses, King of the Persians, and his brother Arsamenes have for Romilda. Christophe Rousset conducts Les Talens Lyriques, with performances by Paula Rasmussen, Ann Hallenberg, Patricia Bardon, Isabel Bayrakdarian and Matteo Peirone.

Alan Curtis continues his exemplary series of Handel operas for Archiv with Ezio, a 1732 work that has received few modern productions. Its initial limited success and failure to generate much interest until the late twentieth century may have to do with its length (over three hours), its preponderance of recitatives, and the composer's reluctance to use the voices together in ensembles, so that the entire opera, until the final chorus, consists of solo singing. Handel's gift for astute psychological insight and distinctive musical characterization is evident throughout the score, and the recitatives, which are necessary for explicating Metastasio's convoluted plot, are not a problem when they are performed with as much vivid dramatic realism as they are here.

For the 1727 season – the waning days of opera's popularity in London – transplanted German composer George Frederick Handel wrote no less than three operas for the English capital's stage. Tolomeo, rè d'Egitto was the last and least enthusiastically received of them. Unsuccessfully revived in 1730 and then again in 1733, Tolomeo was unperformed for the next 200 years, and even now, it remains one of Handel's least performed and recorded operas. Prior to this Archiv set, only a 1995 Vox recording of the work with Richard Auldon Clark leading the Manhattan Chamber Orchestra had been released in the digital era.

With more than a million copies sold, the soundtrack of Gérard Corbiau's film 'Farinelli' contributed considerably to the international renown of Les Talens Lyriques, in 1994. Back then the voice of the castrato Carlo Broschi, known as Farinelli (1705-1782), was created using a computer to mix the voices of countertenor Derek Lee Ragin and soprano Ewa Mallas-Godlewska. On stage, in 2011, rather than a falsettist, world-renowned mezzo Ann Hallenberg, was chosen by Christophe Rousset to portray the first rock star in the history of music.

With The Farinelli Manuscript Ann Hallenberg, accompanied by Stefano Aresi and Stile Galante, offers a scintillating reading of the music known to have been sung by the castrato Carlo Broschi during his 23-year stay in Spain (and sent as a present to the Empress Maria Theresa). Described as “a force of nature”, displaying flawless coloratura and a purity of timbre, the Swedish mezzo follows her previous appearance on Glossa with Aresi (a disc devoted to music associated with the later castrato Luigi Marchesi) with a spirited demonstration of the musicality which so attracted Farinelli to listeners at the Spanish court.

For his 3rd album on Phi, his new label published by the group Outhere, Philippe Herreweghe has brought together a splendid set of artists in the Lutoslawski hall in Warsaw. Ann Hallenberg, whose voice won over the public of some of the world’s most prestigious concert halls, takes on the Rhapsody for contralto solo and men's chorus by Brahms while the rest of the programme leads the listener through his essential works for chorus and orchestra. Herreweghe’s long-time affinity with the composer of A German Requiem has enabled him to provide a coherent and personal vision of those musical pages in which Brahms gave free course to his most intimate thoughts.

This is the world-premiere recording of L’Oracolo in Messenia, an opera prepared by Vivaldi for Vienna and now reconstructed by Fabio Biondi. He leads this triumphant performance, which opened the 2011 Resonanzen festival in the Austrian capital with a high-powered cast including Ann Hallenberg, Vivica Genaux and rising soprano Julia Lezhneva.

Musical maverick Martin Fröst’s most ambitious Sony Classical release yet sees him as both clarinetist and conductor, joining soloists Lucas Debargue (piano), Ann Hallenberg (Mezzo-Soprano) and Elin Rombo (Soprano) and the Swedish Chamber Orchestra, of which he is chief conductor, in a double-album of masterpieces capturing the paradox of Mozart’s fragile existence and extraordinary creativity.

Born in Venice, Antonio Sartorio (1630-1680) composed 14 operas. He often made the long journey from Hanover, where he held the post of Maestro di Capella to the Duke of Brunswick, to compose and present new operas in his native city and recruit musicians for the German court. He is credited with introducing Italian opera to the Hanover court in 1672. Sartorio finally returned to Venice to be Maestro at St Mark’s where he composed sacred music, albeit not as much as the renowned Coffi might have been expected of him in that position.

Danish soprano Ditte Andersen and Swedish mezzo-soprano Ann Hallenberg were heard to stunning effect in Spedidam's splendid 2006 recording of Gluck's Aristeo and Bauci e Filemone with the ensemble Les Talens Lyriques under Christophe Rousset. Here they tackle another obscure corner of the Baroque: cantatas and operatic arias discovered in the libraries of the palaces at Meinungen and Sonderhausen, many of which were previously unknown. The Italian composers represented include a few who are well known, but they are predominantly obscure – Antonio Caldara, Giovanni Battista Bononcini, as well as his brother Antonio, Francesco Gasparini, Giovanni Battista Alveri, Giuseppe Maria Andrea di Orlandini, Attilio Ariosti, Giovanni Porta, and Tommaso Bernardo Gaffi.

Diving into Vivaldi's Orlando furioso with Jean-Christophe Spinosi, Matheus Ensemble, and a shockingly good cast is enough to make even the most jaded listener smile. It is fresh, unrelentingly impressive, and entertaining to a fault. The opera is over-plotted: the first paragraph of the synopsis is enough to confuse anyone not taking notes. And listening to the entire thing would amount to more flowery, athletic vocalism than most can stand in one sitting. But those with the remotest interest in Vivaldi opera, or opera at all, will be hard pressed not to marvel at the quality of what's recorded here. Spinosi is a brilliant Vivaldian who pulls sweet-toned lyricism and down-and-dirty sawing from his Matheus Ensemble, making the most of the composer's rich orchestration. And the cast pulls one rabbit after another out of its collective hat, tackling Vivaldi's consummately difficult arias with élan.
