La Clemenza di Tito can be rather bloodless, but in this instance an elegant, vocally impeccable cast makes up for much of the lack of drama in John Pritchard’s conducting. Werner Hollweg’s pingy tenor cuts through the orchestra brilliantly, and he uses his voice very well. Teresa Cahill and Anne Howells are an attractive-sounding pair as the young lovers, and Robert Lloyd is typically strong as Publio. The honors here go to Yvonne Minton’s anguished, beautifully accurate Sesto, capturing an often under-valued mezzo in one of her best roles. Janet Baker is Vitella, bringing fire and passion to her melodramatic utterances and immaculate singing to a very challenging role. The sound is excellent.

The eminent teacher and theoretician Ferruccio Busoni was revered throughout all Europe at the turn of the century, but his unclassifiable music became overshadowed by other avant-garde movements such as the Second Viennese school. By 1916, his unconventional, innovative opera Arlecchino is a caustic farce about the war, and includes sprechgesang that very much inspired him since he held a performance of his friend Schoenberg’s Pierrot lunaire in his own house. The featured version is conducted by Sir John Michael Pritchard and was the first ever to be put on record.

This performance from the 1950s sounds surprising after decades of authentic performance. The instruments are modern, the forces large and the style of singing rich, full and almost romantic. Yet the effect is electrifying. All the performers sing with such conviction that this Poppea moved me and it makes some authentic performances sound thin and academic by comparison.

This epic opera inspired by Shakespeare's tragic masterpiece was written in 1847, but did not receive its British premiere until 1938 when it was presented for the first time at Glyndebourne. The tragedy is a penetrating, concentrated, and harrowing study of the ambition of Macbeth and his wife, Lady Macbeth. In the end both seem to verge on hallucination and madness as they recoil from the mayhem they have created around them. The production features an outstanding international cast, with the Greek baritone Kostas Paskalis in the title role and British star Josephine Barstow making an exciting debut as Lady Macbeth. Proceedings are conducted by the sympathetic baton of John Prithard.

Le Nozze di Figaro, Mozart's timeless opera buffa, is one of the greatest of all operatic masterpieces. It is based on Beaumarchai's comedy Le Marriage de Figaro and tells the tale of the servant Figaro, who is about to marry the maid Susanna. Count Almaviva, keeping an eye on Susanna himself, tries to prevent this marriage with the help of Bortolo, the doctor, but is continually thwarted.

Joan Sutherland who, three years earlier had wowed the world with her Lucia, easily accomplishes the act 1 coloratura… She does manage to inflect emotion into Violetta’s solos in act 3 with a particularly poignant rendering of the letter scene. Bergonzi’s Alfredo in this recording is one of his best assumptions on record. His voice is at its lightest with near perfect legato and with phrasing that other tenors can only aspire to.
