Chamber music has featured only intermittently in the output of Krzysztof Penderecki who, during the last forty years of the 20th century, focussed mainly on operatic, choral and orchestral works. The present disc includes several shorter pieces from either end of the composer’s career, as well as one of his most substantial instrumental works to date, the Second Violin Sonata, which recalls not only the composer’s own First Violin Concerto (Naxos 8.555265) but several late pieces by Schnittke and the Eighth Quartet of Shostakovich. This is its world première recording.
