In spite of the fact that Sibelius’ chamber music is far less well-known than his orchestral works, it forms a large and important part of his production. In terms of numbers of discs it makes up a fourth of the complete recorded edition being brought out on BIS. Already released are the complete quartets and piano trios [BIS-CD-1903/05] and the works for violin and piano [BIS-CD-1915/17]; the present set focuses on his chamber music for other instrumental combinations and includes a number of world première recordings and previously unreleased material. A substantial chapter is the music for cello (solo and with piano accompaniment), much of which was written for Sibelius’ brother Christian. It is here performed by Torleif Thedéen, with the support of Folke Gräsbeck on the piano. There are also a number of duos and trios for strings, including the brief Vattendroppar (Water Drops) for violin and cello pizzicato, which is often claimed to be Sibelius’ earliest surviving composition, dated to around 1875. Another, more sizeable, rarity is the music to the play Ödlan (The Lizard), scored for string ensemble. Composed in 1909, half way between the Third and Fourth Symphonies, it was once described by Sibelius as ‘one of the most exquisite works that I have written’. This volume also includes Sibelius only work for viola and piano (‘Rondo in D minor’), as well as the world première recordings of two pieces for solo kantele, the traditional Finnish plucked-string instrument which appears in the Kalevala, the Finnish national epos that served as such an inspiration to Sibelius. Another group of works with a specifically Finnish background, are the pieces for ‘torviseitsikko’, a particular combination of seven brass instruments and percussion. These are here performed by members of the eminent German ensemble brasspartout. A varied programme then on this ninth instalment of the acclaimed Sibelius Edition, about which a reviewer in Fanfare has already predicted that it ‘will certainly be considered a landmark in the history of recording’.

Torleif Thedéen and Roland Pöntinen, who with this disc give us the larger part of Schnittke's chamber music for the cello, are long-time partners whose first joint recording for BIS was made in 1986 - entitled 'The Russian Cello', it incidentally included a performance of the first of Schnittke's cello sonatas. Since then the two have appeared on a number of discs together, performing works by Prokofiev, Rachmaninov, Hindemith and Anton Webern among others. Their recording of the Chopin Sonata, coupled with works by Robert Schumann, was highly acclaimed in The Gramophone, whose critic found that the team gave 'this wonderful music a sweep and gradeur that's immensely satisfying'.

Aram Khachaturian was an established Soviet artist when he realized an old dream of his in the first postwar year 1946 and composed a grand, quasi-symphonic work for his main instrument. Following his spectacular concertos for piano and for violin, which in the meantime had taken the world by storm, he now surprised his public with music that only gradually reveals its fiery temperament: we hear very clearly how well the composer knew the violoncello, the instrument on which during his study years he had practiced until his fingers hurt, in all its special qualities and how precisely he knew how to bring out its expressive and velvety autumnal personality. Neither this concerto nor the Rhapsody composed by Khachaturian seventeen years later for Mstislav Rostropovich can be mastered with mere virtuoso ostentation. Both works demand the services of a soloist who does not misunderstand the unprecedented difficulties of his parts as an opportunity for self-display, and Daniel Raiskin has found such an interpreter in the person of the Swedish cellist Thorleif Thedéen: sovereign in every technical respect, he surmounts the enormous challenges even when he removes himself from the intensive dialogues with the orchestra and – left entirely to his own devices – captures the whole of Khachaturian in the monologues.

Ingmar Bergman (1918- 2007) made fifty films, directed more than 150 theatre productions and wrote several books, but the recurrent thread running through his life was music. He often said that if he hadn't become a director he would have wished to become a conductor, and went so far as to claim that ‘film and music are almost the same thing. They are means of expression and communication that go beyond human wisdom and that touch a person’s emotional centre.’ Bergman’s interest in classical music became evident early on in his career. Music in Darkness (1948) is about a pianist who loses his sight in a shooting accident. To Joy (1950) features a violinist who dreams of a solo career and Summer Interlude (1951) takes place at the Royal Swedish Opera. He admired all who could perform music, reserving his greatest love for pianists, and concert pianists are portrayed in Hour of the Wolf, Face to Face and Autumn Sonata. One of Bergman’s favourite Swedish pianists was Roland Pöntinen, who here performs a number of pieces featured in Bergman’s films, by composers including Mozart, Chopin and Schumann. Pöntinen is joined by the Stenhammar Quartet in the second movement of Schumann’s piano quintet, used by Bergman to great effect in the award-winning Fanny and Alexander. Another of the director’s favourite performers, the cellist Torleif Thedéen, also contributes to the project, with the sarabandes from three of Bach’s suites for solo cello.
