George Benjamin - Viola, Viola, for viola and viola (1997)
0:00 The violas almost imperceptibly trade a monotonic line, with increasing interjections by vibrant triple stops and furtive runs. 1:29 Misterioso. More colors of the violas are brought forth, with a persistent coarse 2-note motif. 3:34 Cantabile. Independent lines begin to flourish, often colored by bright thin harmonics. 6:41 Climax of wide sonorous chords and tremolos 7:58 Reverberant pizzicato chords, enhanced with artificial harmonic echos, close out the piece.
