The Arditti Quartet travels the world with only contemporary works on their music stands. When they sometimes do play early music, like the two most famous songs by the Elizabethan composer John Dowland, they use a 2012 arrangement by the Mexican composer Hilda Paredes, excellently complemented by her own “Canciones Lunáticas”. Salvatore Sciarrino, in contrast, has chosen one of the most unusual texts ever set to music: the infinitely sad catalogue of the posthumous estate of painter Andrea del Sarto, who died penniless in Florence in 1530. The composer lets us hear the depths that can hide behind a simple list. Much like Leoš Janáček, who turned unrequited love into a gripping string quartet.
