This unusual coupling works surprisingly well, God only knows why. Perhaps the Britten’s neo-classical (or Baroque) leanings and formal freedom sit well next to Beethoven’s echt-Classical language, but whatever the reason the performances of both works are extremely fine. Paavo Järvi’s expertise in Beethoven with the Deutsche Kammerphilharmonie Bremen is by now well-known, and in Janine Jansen he has a soloist who matches him for vibrancy and freshness.

Janine Jansen embarks on a journey recording on 12 of the world's most precious instruments. "All 12 violins are by the master Italian luthier Antonio Stradivari and have been played by an encyclopedic list of great violinists. Each of them has its own distinctive sound and character which violinists normally have months, if not years, to respond to and make their own. Jansen had only a matter of days with these violins before going into the recording studio accompanied by Sir Antonio Pappano.

Given how often these chamber works by John Harbison are played in concert, it is somewhat surprising that this is the first CD to offer them on one program. At once highly abstract, completely accessible, and intensely personal, Variations and Twilight Music were written in the 1980s and have become classics in their own right, fitting comfortably alongside the likes of Bartók’s Contrasts and Brahms’ and Ligeti’s respective Horn Trios. Although both pieces on this recording were taken from live performances by the fine members of Spectrum Concerts Berlin, the sound is not compromised in the slightest.

Even though violinist Janine Jansen appears alone in the cover photo of this 2012 Decca release, and her name is featured in large letters, no one should mistake this album as a solo effort. The recordings of Franz Schubert's String Quintet in C major and Arnold Schoenberg's sextet Verklärte Nacht are ensemble performances, and the musicians who play with Jansen form an artistic bond that seems utterly at odds with the star-oriented artwork. Jansen is certainly behind the choice of works, because they were programmed on her critically praised concert at Wigmore Hall.
