Vittorio Ghielmi is known for the intensity and versatility of his musical interpretations and for his new approach to the viola da gamba and the sound of the early music repertoire. His ensemble, Il Suonar Parlante, is devoted to investigating early music repertoire and has also performed with jazz, flamenco and traditional Asian musicians.

Johann Gottlieb Graun (1702/3-1771) began his musical studies at the famous Kreuzschule in Dresden. Subsequently he acquired his legendary prowess on the violin from two of the most excellent teachers of the time: the Vivaldi disciple, Johann Georg Pisendel in Dresden and Giuseppe Tartini in Padova. Very early in his career, during his service as concertmaster in Merseburg, Graun got acquainted with Johann Christian Hertel (1697-1754), an outstanding viola da gamba virtuoso; they remained friends throughout their lives, corresponding frequently. This may be the reason for Graun's apparent knowledge of the technical possibilities of the viol: his compositions for this instrument - not less than 22 large-scale works are extant - bear witness to this.

Dorothee Oberlinger is one of the most amazing discoveries of recent years, an expressive virtuoso who has received numerous awards. Today she is seen as one of the best recorder-players in the world. Her concerts have been received with enthusiasm by critics and audiences alike, earning her unanimous acclaim. Her CDs are regularly fêted as the best new issues on the market.

This disc presents a programme of Concerti by the brothers Johann Gottlieb and Carl Heinrich Graun. Unfortunately the brief attributions ‘del Sig re Graun’ or simply ‘di Graun’ on the manuscripts mean the Concerti cannot always be assigned with certainty to one or the other. Nevertheless these Concerti, performed by Cappella Academica Frankfurt, are full of colour and contain all the stylistic idioms of the transitional period between the Baroque and Classical periods.

Brothers Johann Gottlieb and Carl Heinrich Graun were highly influential and popular figures in 18th Century Berlin. As musicians of the court of Frederick the Great, Carl Heinrich became an important figure at the new Berlin Court Opera, while Johann Gottlieb strongly influenced early classicism in general as a violinist and composer. The name Graun was like a seal of approval in those days for zestful music rich in ideas, displayed perfectly by this collection of concertos. Oboist Xenia Löffler, a member of the Akademie fu"r Alte Musik Berlin, has distinguished herself as a specialist for the North German repertoire of this period.

The present richly enjoyable CD contains five trios by Johann Gottlieb and Carl Heinrich. In some areas of the brothers’ work it is near enough impossible to know who wrote what with any certainty – as Grove puts it “problems of attribution, chronology and biographical detail remain”. Manuscript attributions usually refer simply to ‘Graun’.

The year 2012 marks the tercentenary of the birth of Frederick the Great, whose political and military glory has often relegated his musical talent to the status of a mere hobby. But Frederick II was not only the key personality of Berlin musical life for the whole of the 18th century – as is shown by the works of the composers presented on this CD, all of whom worked at his court at some point in their careers – but also an excellent flautist who left posterity a number of fine flute sonatas from his own pen.

Johann Gottlieb Graun and his slightly younger brother Carl Heinrich Graun both worked in the Berlin-based court of Frederick the Great, whose musical cabinet also included Carl Philipp Emanuel Bach. Superficially, the music of the Grauns can seem similar enough that in terms of attribution, their works are often confused, particularly when "Graun" is the only name provided on a given manuscript. Curiously, at least concerning the track listing, Accent does not try to identify which of the four concerti on their Graun: Concerti belong to Johann Gottlieb and which to Carl Heinrich. When one gets a little deeper into the notes, the truth is known – the first concerto, in A major for viola da gamba is by Johann Gottlieb, and the other three are the work of Carl Heinrich.

The closing disc in London Baroque’s survey of the rise and fall of the trio sonata takes us to 18th-century Germany, and includes works by no less than two Johann Gottliebs: Johann Gottlieb Goldberg – who rose to posthumous fame by being associated with J.S. Bach’s celebrated set of variations – and his namesake Johann Gottlieb Graun, violinist and composer at the court of Frederick the Great. Next to them in the list of contents are also more familiar names, such as Graun’s colleague at the Prussian court, C.P.E. Bach, and the ubiquitous G.Ph. Telemann, here represented with an unusually scored trio for violin, gamba and basso continuo. The programme straddles the divide between late Baroque and Classical music, and several of the included works point clearly at what was to come.

Instrumental works utterly dominate the extensive oeuvre of Johann Gottlieb Graun. It is hardly surprising that among them (besides overtures, symphonies, quartets, trios, and wind concertos) he wrote a great number of concertos and solo sonatas for the violin. He composed at least 83 solo concertos, double concertos, and several ensemble concertos with solo violin. The concerto by Markus Heinrich Grauel on this CD may be taken as an example of Graun's influence.

Many important Baroque composers and their music found their way to Denmark – thanks not least to the music-loving King Frederik IV. This CD presents a unique musical panorama of the King's court music and combines concertos by Christoph Graupner, Johann Adolph Scheibe and Johann Gottlieb Graun with newly discovered dance music for the King’s daughter, Princess Charlotte Amalie, reconstructed for this world premiere recording by Danish recorder virtuoso Bolette Roed and the Polish Baroque ensemble Arte dei Suonatori.

Of all the composers who wrote for the gamba during his times, Johann Gottlieb Graun must have been the most diligent one, even though he was not a virtuoso on this instrument. The twenty-seven works by him that are known to us represent significant contributions to the repertoire of the concerto, cantata, and sonata. All three of the works presented here contain grand solo parts for the viola da gamba that prove to be of the highest virtuosity. Graun evidently was interested in putting a virtuoso to the test.
