The string trio is one of my favourite formats; it doesn't have the baggage of the string quartet: that daunting mass of masterworks from Haydn to the present day. The String Trio has, on the one hand, the light serenade side, and on the other the intensity of great string trios by Schoenberg, Villa-Lobos and Schnittke. In the middle is the perfection of Mozart's great string trio from 1788, the Divertimento, K. 563.
The first two works chosen by the exceptional group Leipziger Streichtrio - violinist Adrian Iliescu, violist Atilla Aldemir and cellist Rodin Moldovan - try for that Goldilocks medium attained by Mozart. This is joyful music, but not completely ignoring dark undercurrents. Ernö Dohnányi's Serenade for String Trio, Op 10, is a relatively early work, written in 1902. It takes as its formal model not Mozart's Divertimento, but rather Beethoven's Serenade for String Trio, op. 8, from 1796-97. Jean Françaix's String Trio, from 1933, is a neo-classical gem, which exemplifies the modus operandi of Les Six: slightly sad nostalgia, slightly ironic romps, slightly erudite fugal passages, always having fun with serious matters.
Jean Sibelius's String Trio, which dates from 1894 is a more serious beast. This is an almost altogether stern work, and though it's only 8 minutes long, it has a symphonic feel to it. When have you ever seen Sibelius smiling in a portrait? *
There are two additional pieces in this interesting program, which one might consider encores. George Enescu's Aubade, from 1899, is a bit of fun, a rustic folkloric piece full of swoops and pizzicati. Andras von Toszeghi's arrangement of J. S. Bach's great Chaconne from the 2nd Partita for Solo Violin is substantial, and interesting. Mozart himself transcribed six Bach Preludes & Fugues for string trio in 1788, K. 404a. I love listening to the Chaconne in any guise - I especially enjoy Brahms' version for piano, and Leopold Stokowski's for full orchestra. But this isn't quite a complete success as an arrangement - the violin gets to keep most of the good bits, and the viola and cello have the leftovers that make the soloist sweat while double-stopping in the original. It's neither fish nor fowl, but tasty anyway! Altogether this makes an exceptional hour of music.
* Here's your answer: Werner Bischof very nearly got a full smile out of Jean Sibelius in this 1948 portrait.
