Our collection of previously unknown Christmas oratorios is growing impressively and happily. After Joseph Eybler in October, I can even announce two trouvailles for this month. There is the Christmas Oratorio by Carl Heinrich Graun (1703-1759), the conductor of Frederick the Great. It was only recently found in Washington. A precise dating is not yet possible, but it certainly arose in Graun's pre-Berlin time in Dresden or Braunschweig. However, it is a masterpiece on the threshold of a sensitive style. The well-balanced alternation of melodically accented and contrapuntally rigorous choral movements, of soulful, colorfully orchestrated arias and harmoniously far-reaching recitatives is particularly impressive.

Richard Jones's radical new production of Lohengrin was the talk of the 2009 Munich Festival. It was also a triumph for Jonas Kaufmann in the title role. Die Welt added that they "could not think of any cast more perfectly matched, so youthfully enthralling, in short: so wonderful … ". With striking costumes and designs by Ultz - and directed by Maestro Kent Nagano - it represents a bold new Lohengrin for today's world.

These sonatas for violin and continuo, dating from the court of the Holy Roman Empire in Innsbruck in 1660, are little known; perhaps the only other recording of them is a later one by their champion, Andrew Manze. If you like the woolly world of seventeenth century violin music, this composer belongs in your library. The later recording, which includes all the sonatas, lacks the theorbo heard in this 1992 performance, presumably reissued by Channel Classics in order to compete with Harmonia Mundi's release, but both are superb. The music's neglect is largely due to Pandolfi Mealli's obscurity; nothing is known of him beyond this group of works – not even whether a Sicilian composer named Pandolfi working around the same time was the same person or not.

It was a good idea to assemble three pieces associated with Bach’s first Christmas at Leipzig. The Cantata No. 63 and the earlier E flat version of the Magnificat were both performed at Leipzig on Christmas Day, 1723, and it may well be that the D major Sanctus was also sung at the same services. Not all of the music, though, was newly written for the 1723 Festival. The Cantata was already in existence perhaps as much as ten years earlier when Bach may have performed it at Halle as his trial piece for the post of organist of the Liebfrauenkirche in which he was interested. There are notable differences between the E flat version of the celebrated Magnificat and the later, more frequently performed version in D major.

Georg Böhm is one of those German Protestant composers who has had the misfortune to have his name inextricably linked with that of J. S. Bach. In the case of Böhm, the link with Bach is especially potent, since there is the liklihood that the two became acquainted during the period Bach attended the Michaelisschule in Lüneburg (1700?c. 1703). More importantly, Böhm has long been acknowledged as an influence on Bach?s organ and keyboard music.

Harry Christophers and The Sixteen present a vivid and joyful account of the Christmas story in this recording; Mark Padmore makes another appearance in the Evangelist role, with Michael George a convincing Herod and Libby Crabtree an appropriately light-voiced Angel.

This world premiere recording reveals a new masterwork by the 18-century Italian master Giovanni Battista Pergolesi, brilliantly reconstructed by musicologist Malcom Bruno from the composer's single-movement woks. Most of this music has been lost or forgotten since its creation more the 250 years ago, and most, if not all, has never been recorded.

Viele versuchen es, aber wenige erreichen es: das Kunststück, als Popkünstler und Alte-Musik-Experten zu gleicher Zeit authentisch zu wirken. Dass sie zu denen gehört, die es erreicht hat, macht Hille Perl zur Ausnahmekünstlerin. Mögen sie und ihr Partner Lee Santana sich auch inszenieren – in ihrem Spiel gelingt der stets schwarz gekleideten Rotweinliebhaberin eine so vollkommen natürliche Verbindung zwischen Sinnlichkeit und melancholischer Endzeitbetrachtung, dass moderne und barocke Lebenslust, heutige Weltflucht und barockes Memento mori zu einem Lebensgefühl zu verschmelzen scheinen.

In the Baroque period, the duetto da camera, usually conceived for two equal voices and continuo, was an important form of vocal chamber music, of which innumerable examples are found in the works of composers associated with Venice, the leading protagonist in the history of this genre. Venetian Sara Mingardo is joined by a large group of young, talented solo female voices (Silva Frigato, Lea Desandre… ) in this amazing project, where masterpieces by the leading composers of the time have been entrusted to the voices best suited to highlight the respective particular musical content.

Boris Godunov is a work that, with its long, continuous scenes and monumental structure, does not lend itself easily to a highlights disc, especially if the intention is to give a fair cross-section of the opera. The producers of this compilation, drawn from a complete recording originally issued by Erato, wisely concentrate the choice on a few substantial chunks, covering most of Boris’s part. To this they add a couple of snippets that can stand on their own, out of context.

John Cranko’s mastery of the art of the pas de deux finds its climax in Onegin, one of the most successful full length ballets of the 20th century. Set to sweeping music by Tchaikovsky, it tells Alexander Pushkin’s tragic love story of the world-weary aristocrat Onegin and the naïve country girl Tatiana in a superbly nuanced way. Featuring world stars Friedemann Vogel and Alicia Amatriain, this production is a must for all lovers of dramatic – and romantic – ballets. With Onegin, John Cranko secured his place in the pantheon of great 20th century choreographers. He created the three act work for the Stuttgart Ballet – of which he was Director – in 1965 and revised the ballet two years later.

Francois-Xavier Roth and Les Siècles present a fascinating new interpretation of Mahler's Symphony No.1. It features the first period instrument recording of the 1893-94 version, using a performing edition prepared by musicologists Anna Stoll Knecht and Benjamin Garzia, working in collaboration with Universal Edition. Initially presented as a symphonic poem entitled Titan, the work was met with severe criticism as it developed. This fascinating reconstruction using the composer's Hamburg and Weimar manuscripts testifies to the genius of one of the greatest symphonists of the modern era.

The music of Johann Strauss reflects a lifestyle, a refinement … a true Viennese tradition. At the same time, this music simply creates joie de vivre, an almost uncontrollable urge to dance. It is these feelings and these emotions Anima Eterna and its leader, Jos van Immerseel communicate with delicacy and conviction; also with a view to the greatest possible proximity to the score as it was conceived at the time of its creation.
