This intriguing encounter between early Romantic and “spectralist” interleaves Schumann’s Fünf Stücke im Volkston and Op. 73 Fantasiestücke, two cello solos by Murail and his engaging Une lettre de Vincent, for flute and cello, culminating in his version of Schumann’s Kinderszenen. Odd to retain the instrument that you’re transcribing from, but the piano originals are energised and haloed by captivating new timbres.
