Pieces for string quartet figure very prominently in Alberto Posadas’ output. The Spanish composer’s five-movement Liturgia Fractal is one of the most impressive quartets of recent times, and it is the three movements involving string quartet that provide the framework for the arc-like structure of Sombras, a 75-minute sequence inspired by The Book of Delusions by the Romanian philosopher and nihilist Emil Cioran. A lengthy setting for soprano and quartet of a passage from Cioran’s text forms the centrepiece of the work, flanked by brief transitions for soprano and viola, and soprano and clarinet, while the first and last movements feature the string quartet, with the addition of bass clarinet in the finale.
