Stephen Johnson visits Wootton Upper School in Bedfordshire for an exploration of Shostakovich's two very different trios for piano and strings. The first was written in 1923 when the 17-year old composer was a student at the St Petersburg Conservatoire. At that time, Shostakovich often played music to accompany films at a local cinema, and his sister remembers Shostakovich being booed and whistled by the paying audience when he and his friends tried playing the trio along to the movies! A recording of the slow movement of Shostakovich's second trio was played at the composer's memorial service in 1975; it's a much more mature work, full of emotion, but also full of sardonic humour: grotesqueries which act as thinly veiled stabs at the Soviet dictatorship of Jozef Stalin. It also contains some fascinating Jewish music in the finale - something Shostakovich had been particularly intrigued by in his middle years: "Jewish music has made a most powerful impression on me. I never tire of delighting in it; it is multifaceted, it can appear to be happy when it is tragic. It is almost always laughter through tears". The programme ends with a complete performance by The Kungsbacka Trio, of Shostakovich's Piano Trio No.2 in E minor, Op.67.
