By commission of the Siemens Foundation for Irvine Arditti and the Arditti String Quartet, Felder has created a work of dynamic contrasts. From the outset, he asks much of the strings (Fiery - very aggressive!) through a sustained fortissimo passage, shifting quickly to alternate states (suddenly subdued) and effects (effervescent). Afire, intense, perky, even mechanically!'incessant are instructions throughout. For advanced performers. Duration: 17'30'
