Naïve continues its admirable series of complete recordings of Vivaldi's operas with Atenaide, an opera seria that was not successful at its 1728 premiere, and received no further performances during the composer's lifetime. This recording was made as a result of the first modern production, which was presented in the same Florentine theater in which the opera had received its premiere. With an unusually convoluted plot, and lasting over three-and-a-half hours, its unlikely that Atenaide will ever make its way into the repertoire, but especially for the Vivaldi enthusiast and the lover of virtuosic Baroque vocal display, the opera should be very attractive.

The 70 operas by Ferdinando Bertoni (1725 - 1813) are almost all forgotten, except for his Orfeo. The opera is based on the same libretto as Gluck's Orfeo ed Euridice, and was also composed for the same castrato, Gaetano Guadagni. Unlike Gluck however Bertoni created a true-opera scenario, which celebrates its rediscovery here in this recording with Vivica Genaux.

Genaux brings a fascinating swagger to the solo motets. Her chest voice has a baritone richness; in higher registers, she can sound virginal or diva-ish. Zooming through scalar passages and leaping around registers, she turns doggerel Latin into moving statements…Urged on by Dubrovsky, the Bach Consort Wien bustles through [the Kyrie and Credo]…this performance would make Vivaldi proud.

This 3CD box unites three recitals that showcase the virtuosity, elegance and expressivity of mezzo-soprano Vivica Genaux. Together, the programmes, recorded between 2003 and 2009, offer a survey of the repertoire that has figured most strongly in Genaux’s career – music from the 18th and early 19th centuries by Vivaldi, Handel, Hasse, Rossini and Donizetti. The spectacular recital of arias by Vivaldi, ‘Pyrotechnics’ was nominated for a Grammy Award in 2010.

Rinaldo, Handel's first Italian opera, is still arguably his best Italian opera. Or, to put it another way, Handel found what worked – hair-raising arias, affecting harmonies, colorful orchestrations, wild special effects, and a story that his English audiences would accept as a compliment to their own magnificence – and he stuck with it until the English were sick of Italian operas. Handel's Rinaldo works wonderfully well in this recording directed by Rene Jacobs. Jacobs makes the drama work, making one believe in the unlikely coincidences that constitute its plot. He makes the theatrical effects work, making one believe in Handel's monumental thunder that precedes the arrival of the evil queen.

No Handel opera is as enigmatic as Silla. His fourth London opera, it was composed in 1713 to a libretto by Giacomo Rossi, also the librettist of the composer s first great London triumph Rinaldo (1711). And that is just about the extent of any certainty on the subject. It might have been premiered in 1713 in London in a private concert at the Queen s Theatre, but even this remains unconfirmed. This is one of Handel s few historical operas, being concerned with Plutarch s account of the latter part of the life of Lucius Cornelius Sulla, who after taking Rome became a tyrannical despot who murders his opponents, before suddenly retiring to his country estate to enjoy his leisure.

Handel's 1738 opera Serse (Xerxes) baffled audiences at first hearing with its mixture of tragedy and comedy, but that same mixture has resulted in the opera's steadily rising status in performance today. If you're maxed out on athletic opera seria performances, check it out: it has elements of a put-on of that genre. The plot is kicked off by Serse, the king of ancient Persia, praising a shade tree in the famous aria "Ombra mai fu," whose tune is also known as Handel. The role of Serse is written for a male countertenor (originally the castrato Caffarelli), who has to keep a level of seriousness as his character becomes involved in increasingly improbably romantic triangles.

With this exciting release, Fabio Biondi, the outstanding Europa Galante, and a cast led by stars Véronique Gens and Vivica Genaux strike a decisive blow for Alessandro Scarlatti's obscure Oratorio per la Santissima Trinità. Old-fashioned even in its day, the work is a musicalized instructional debate about the mysteries of the Holy Trinity between the allegorical personae of Faith, Theology, Faithlessness, Time, and Divine Love. If you're asleep already, it's for good reason. The libretto is the definition of dry – boring both for its rhetorical contrivance and its verbosity. But before you run for the nearest exit, know that Scarlatti responded to this uninspired mess of ideological bickering with outstanding music, entertaining from beginning to end. Drawing only on a small ensemble of strings and continuo, he created an improbably diverse-sounding score full of infectious rhythms, appealing vocal melodies, and rich textures.

A year after the two hundredth anniversary of Gaetano Donizetti's birth (1797) and 150 years after his death (1848), the Teatro de la Maestranza de Sevilla chose to open its 1998-9 operatic season with four per­formances of Alahor in Granata, an almost for­gotten opera by the composer. This is an event al a huge historical importance since it marks the first time that the opera has been performed in the XXth century. Alahor in Granata was first performed in the Teatro Carolino in Palermo on the 7th of January 1826 but, alt­hough the opera was again staged in the same city in 1830, it later passed into oblivion and has never been performed ever since. Up until now, as was the case with many of Donizetti's works, a hundred and seventy two years after its pre­miére, we had very little news about this beauti­full masterpiece's original fate.

The history of opera is inseparably linked with the biographies of singers; audiences have always been fascinated by both musical prowess and behind the scenes goings-on. The battle for prestige and fame was heated and passionate in the Baroque era, with legendary rivalries. Fiercely competitive, Cuzzoni and Bordoni were among the most acclaimed divas of the age, resorting to fisticuffs on stage. Present-day prima donnas Genaux, Prina, Nesi and Basso now follow in the footsteps of their fervid predecessors, presenting on disc a tongue-in-cheek survey of standout arias for mezzo soprano and contralto.

There is no complete surviving score for Vivaldi's Ercole su'l Termodonte, but there is enough existing material that modern scholars have been able to reconstruct it primarily by making new settings of the lost recitatives. The first production of the opera since Vivaldi's time was at Spoleto in 2006 in a version by Alessandro Ciccolini, which was released as a DVD. Conductor Fabio Biondi made a version introduced in Venice in 2007, which is recorded on this 2010 Virgin CD. Biondi's recording has the advantage of two international superstars in the leading roles, tenor Rolando Villazón and mezzo-soprano Joyce DiDonato, and soprano Diana Damrau is nearly in their league. Villazón's earthy voice is usually associated with 19th century and verismo Italian repertoire, but he has an acute sensitivity to Baroque vocal style, and his robust, almost baritonal tenor is entirely appropriate for a larger-than-life character like Hercules.

Composed for the Carnival season in Verona in 1735, Bajazet is a ‘pasticcio’ opera based on the familiar story of the eponymous Turkish sultan’s imprisonment at the hands of the Tartar tyrant Tamerlane. As such, it openly uses arias by other composers, including Hasse, Broschi and Giacomelli, as well as re-cycled pieces from Vivaldi’s own operas (L’Olimpiade, Giustino, Farnace, Semiramide and Montezuma among them). But this is no mere patchwork of recycled numbers. All the ‘borrowed’ arias are expertly placed within the dramatic fabric of the work and are held together with richly composed recitatives. What we end up with is the best of the best in terms of Neapolitan-style opera – tuneful, virtuosic and passionate. Virtually every number in this recording is a highlight. What really lifts the recording is the quality of the performances. There are no holes or flaws among the experienced cast.

An ideal constellation: 2009 marked Haydn's anniversary year as well as Nikolaus Harnoncourt's 80th birthday. For this occasion the maestro chose 'Il Mondo della Luna', a delicious mixture of satire, comedy and science fiction based on a popular comedy by Carlo Goldoni. Haydn's music unleashes a display of fireworks performed with irresistible energy by Harnoncourt and his ensemble. Renowned actor and director Tobias Moretti relates the story as a magical fairy tale infused with slapstick and fantasy costumes.

One of Handel’s rarer operas, Arminio, set at the time of the Roman Empire, was first performed in 1737. “On the evidence of this very fine recording,” said Gramophone when this performance first appeared, “it can stand among the best of the Handel operas, full of beautiful and imaginative things.” Conducting a cast led by the virtuosic Vivica Genaux in the title role – composed for the castrato Domenico Annibali – is the renowned Handel specialist Alan Curtis.

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.
