When we refer to the "Bach Double," most classical music aficionados know what's being discussed: Johann Sebastian Bach's Concerto for two violins in D minor, BWV 1043. Apart from reconstructions, it's his only double concerto for two violins. With Antonio Vivaldi, such an abbreviated designation is impossible, as he has 27 – count 'em – 27 double concertos for two violins.

Their second duo album on Signum Classics, Viktoria Mullova and Alasdair Beatson perform Beethoven’s Sonatas 6, 1 and 8. Just as in previous recordings, they use a copy of an 1805 Walter (a Viennese fortepiano) by Paul McNulty; together with violin strung with gut, these instruments are what Beethoven’s music craves, giving a rich texture and distinct colours between the registers.

Mullova and Anderszewski have thought through every detail of their interpretations - these are performances of exceptionally wide expressive range, from passionate ardor to the dark and turgid to the touchingly melancholic. Mullova and Anderszewski give a wonderful impression of having thought through every detail of their interpretations. Throughout the three sonatas I was impressed, not just by the way they do everything Brahms asks for, but by their evident personal involvement in the music.

The output of the Finnish national composer Jean Sibelius (1865-1957) comprises one of the most fascinating treasure houses of classical music. It includes world favourites such as Valse triste and Finlandia, as well as the most recorded violin concerto of the 20th century. It includes a symphonic cycle that has become one of the most esteemed and popular cycles since Beethoven.

This is the seemingly unavoidable Sibelius/Tchaikovsky pairing, one that has launched many a young career. Itzhak Perlman recorded these very same pieces for his own debut album on RCA, and with this very orchestra under Erich Leinsdorf. That's a fine disc, but Perlman would later surpass those efforts in later recordings. Nor do I find Leinsdorf an ideal partner, with the comically booming percussion in the Sibelius perhaps the biggest audible gaffe. These current readings are much more satisfying overall. Mullova has not redone these pieces, nor is she prone to recording much at all, so these early efforts deserve credit for holding up so well.

This release by violinist Viktoria Mullova and pianist Katia Labèque (their labels, Labèque's KML and Onyx, which Mullova helped found) sees both these well-known artists stepping out from their usual roles. Mullova has been an impressive exponent of the major violin concertos who has moved into Baroque music in recent years with some success, while Labèque is known for her duo-piano work with sister Marielle (KML stands for Katia and Marielle Labèque). They fill their new roles not just adequately but spectacularly.

Viktoria Mullova is one of the most versatile and charismatic violinists to have emerged in the late 20th century, demonstrating a high level of mastery in broad range of repertoires, from Baroque to Romantic and post-Romantic to jazz and crossover. She established her reputation early in the 1980s, winning both the Sibelius and Tchaikovsky competitions and going on to win the Grand Prix du Disc and a Diapason d'Or Award, as well as garnering numerous other honors. Her widely acclaimed 1987 Philips recording of Vivaldi's Four Seasons is ample proof of her sure grasp of the idiosyncrasies of the Italian Baroque, and the freshness and vitality of her playing has made her version a favorite with listeners and critics. Mullova performs with passionate musicality and technical finesse, and Claudio Abbado leads the Chamber Orchestra of Europe in a nuanced, idiomatic accompaniment.

What is striking about Mullova's playing here is her passion, her melancoly, how she takes opportunity to express the moods of the music. If you think that this should be taken for granted, I agree, but unfortunatly it cannot; it is that little extra making the difference between the good performances and the rare ones.

Viktoria Mullova’s first album of Beethoven Violin Sonatas, Nos 3 & 9’Kreutzer’ with Kristian Bezuidenhout, was reviewed enthusiastically by Gramophone magazine. ‘ The sound, in these familiar pieces has a startling clarity’; it went on to say that the period instruments ‘relocate these two works in a darkly Romantic sound world’. For the next volume in a complete cycle, Viktoria is partnered by Alasdair Beatson in the strange and gnomic 4th sonata, the popular 5th ‘Spring’ sonata and the dramatic 7th – Beethoven in C Minor mood – always exciting and turbulent!

Viktoria Mullova renews her partnership with long-term collaborator Ottavio Dantone in a programme of concertos for violin, offering not only the two famous concertos, but two concertos arranged for violin from the 2nd harpsichord concerto, and a concerto for violin and harpsichord which listeners may recognise from its violin and oboe guise – even this was arranged by Bach himself from the original for two harpsichords. Bach himself was a great re-user of material, and many concerto movements (including some from lost concertos) appeared in his cantatas. Mullova and Dantone have worked together for many years, both recording and in concert.

Viktoria Mullova and Ottavio Dantone turn in smashing performances of Bach's six sonatas for violin and harpsichord, plus two additional items: a transcription of Trio Sonata No. 5 (for organ/clavichord) and the Sonata in G for Violin and Continuo BWV 1021. Bach's violin sonatas use the "church sonata" form; that is, they usually have opening slow movements and no quick movements modeled on dance forms. They are also unique in that they are in fact true duets between the right hand of the keyboard player and the violin, rather than solo works in which the violin sings while the harpsichord accompanies with the continuo part.
