Geolier Dio LO SA Atto II

Vivaldi's operas are rarely recorded and even less often performed, but happily they are gradually gaining more exposure. The most familiar and most frequently recorded is his 1727 Orlando Furioso. The fact that it has been on the public's radar is due largely to an excellent 1977 recording starring Marilyn Horne and Victoria de los Angeles, which has been reissued on Erato. The opera has since been recorded twice, and a DVD of a 1989 San Francisco Opera production featuring Horne and Kathleen Kuhlmann has been released. The newer CDs are extraordinarily fine; in choosing between Naïve's 2005 version led by Jean-Christophe Spinosi and this CPO release conducted by Federico Maria Sardelli, the listener is in a win-win position. Both feature stellar soloists, who are also compelling actors, and beautiful orchestral playing.

“This is unquestionably the most vital and authentic account of Idomeneo to date on disc. We have here what was given at the work's first performance in Munich plus, in appendices, what Mozart wanted, or was forced, to cut before that premiere and the alternative versions of certain passages, so that various combinations of the piece can be programmed by the listener. Gardiner's direct, dramatic conducting catches ideally the agony of Idomeneo's terrible predicament – forced to sacrifice his son because of an unwise row. This torment of the soul is also entirely conveyed by Anthony Rolfe Johnson in the title role to which Anne Sofie von Otter's moving Idamante is an apt foil. Sylvia McNair is a diaphanous, pure-voiced Ilia, Hillevi Martinpelto a properly fiery, sharp-edged Elettra.

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.

After a long period of neglect, Handel's 1719 opera Ottone has attracted renewed attention from historical-performance groups. The opera deals with episodes from the life of Otto II, Holy Roman Emperor in the 10th century, a topic so obscure that even for an 18th century audience an "argument" had to be attached to the libretto by way of background information. The opera was highly successful in Handel's own time, perhaps less for its musical value than for the always fun news stories about the stars in Handel's orbit; this time the feature was soprano Francesca Cuzzoni, who refused to sing the aria "Falsa imagine" until Handel threatened to throw her out a window.

In Dualità, an album of arias from nine Handel operas, soprano Emőke Baráth explores “the duality of the female soul – in which sensitivity unites with power” and the potential of the female voice to characterise both heroines and heroes. At the same time, she provides an insight into the careers of her 18th century counterparts, notably the prime donne of Handel’s opera company in London. Baráth is partnered by Artaserse under the direction of Philippe Jaroussky.

The opera is starring countertenor Valer Sabadus - one of opera's most exciting newcomers - now exclusively signed to Deutsche Harmonia Mundi, a division of Sony Classical. Christoph Willibald Gluck, widely known for fundamentally reforming the 'opera seria' wrote some of the greatest and exemplary masterpieces of this great genre before he started his famous reform of the opera. This makes this work a fascinating and enlightening piece in the puzzle for the evolution of opera and the eminent character Gluck. Gluck's setting of La Clemenza was first performed in Naples in 1752, ten years before his first reform opera.

Most of Vivaldi's operas were composed for Venice, but between 1718 and 1720, he was in the employ the Austrian governor of Mantua, and he composed Tito Manlio for the governor's wedding celebration. The wedding never took place, but the opera was performed in 1719. The Mantuan court was very wealthy, and this is clear from the lavish scoring of Manlio: in addition to the usual strings, Vivaldi uses horns, trumpets, oboes, bassoon, two different registers of flutes, timpani and viola d'amore.

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.

Frederico Ricci's Corrado d'Altamura is a dramma lirico that opened at La Scala in 1841. Set in 12-century Sicily, the highly dramatic plot tells of betrayal and then revenge between Roggero, the Duke of Agrigento and his former friend and tutor, Corrado, to whose daughter, Delizia, Roggero has promised marriage - only to break his vows. The great expert in 19th-century Italian opera Julian Budden thought Ricci's serious works 'are worthy to stand beside Mercadante's.' This is the sixth opera in the Essential Opera Rara series and, once again, a vivid impression of the work is captured on a single disc, accompanied by a complete libretto and article by the eminent 19th century scholar, Jeremy Commons.

The central question was always about how much needs to be added to the surviving notes in order to make Poppea viable on stage. Gardiner and his advisers believe that nothing needs adding and that the 'orchestra' played only when explicitly notated in the score and was a very small group.
