There's magic in these musical hills, as conductor Arnold Östman leads an exemplary performance of Die Zauberflöte on original instruments.Sumi Jo's breathtaking Queen of the Night is the queen of intonation, while Barbara Bonny's Pamina is a phrasing angel, from her pianissimo B flats to her gentle, yet heartfelt, "Ach ich fühl's." Singing as comfortably as a folk singer, Kurt Streit's lyrical, yet dramatic, Tamino is manly and heroic. Gilles Cachemaille is an appropriately charming Papageno, and all supporting performances are stellar. This crystal-clear interpretation must be as close to perfection as Mozart probably dreamed. A true treasure.

Tancredi, which was based on Tasso’s epic poem Gerusalemme Liberata and was first heard in 1813, is most widely remembered for its overture, but this excellent Naxos set makes a strong case for the piece. It completely displaces the previous versions from Sony and RCA, and the eminent Rossini scholar and conductor, Alberto Zedda, proves a far more resilient, generally brisker and lighter Rossini interpreter than his predecessors. Sumi Jo is superb as the heroine, Amenaide, in dazzlingly clear coloratura, as well as imaginative pointing of phrase, rhythm and words.

Le toréador, ou L'accord parfait (The Toreador, or The Perfect Agreement) is an opéra comique in two acts by the French composer Adolphe Adam with a libretto by Thomas-Marie-François Sauvage. It was first performed at the Opéra-Comique, Paris on May 18, 1849. It was a huge success and the work regularly appeared in the repertoire of the Opéra-Comique until 1869.

For generations Bellini’s “Norma” has been looked at from the vantage point of the Verismo era at the beginning of the 20th century. Now Cecilia Bartoli unveils the opera’s original pre-romantic style and colour by taking Norma back to its roots. For the first time ever the entire music is recorded with period instruments from Bellini’s time. Traditional cuts are reinstated. Keys and tonalities are put back into place and the music is executed according to Bellini’s own tempo indications.

The outstanding production of Verdi’s Masked Ball at the Salzburg Festivals 1989 and 1990 was Herbert von Karajan’s legacy to the Festival. Supported by a cast of superlative actor-singers in opulent scenery, Sir George Solti agreed to conduct the opera at short notice after Karajan’s unexpected death in 1989. The production had been expected to be a highlight in Karajan’s series of Verdi operas at Salzburg. Karajan’s celebrated ability to unite a cultivated sound with dramatic effects was known to create extraordinary and highly acclaimed opera events. For Un ballo in maschera Karajan planned something unusual: He would not set the opera in colonial Massachusetts, as the censors had forced Verdi to do when he was composing the work, but in Stockholm in the 1790s at the court of King Gustav III of Sweden, as Verdi had originally conceived his work. Together with the film director John Schlesinger and his stage team, Karajan developed a concept that promised theatrical splendour equal to the musical excellence that the conductor and the handpicked cast of singers would surely provide in collaboration with the Vienna Philharmonic Orchestra.
