The second instalment of our ‘Momentum’ diptych offers a mirror image in two pieces never before recorded together: the young fin-de-siècle Strauss in his last chamber work, and the Korngold of the post-war period, still decked in the colours of Hollywood. The fleeting moment of this reflection is captured in the snapshot of this recording, in which Liya Petrova and her partners Alexandre Kantorow and Duncan Ward combine to make the strings of two masterpieces vibrate in sympathy. A unique élan, a momentum to be grasped.
