Experimentu Mundi. Directed by Giorgio Battistelli, with Nicola Raffone on percussions, Peppe Servillo narrator, and artisans of the city of Albano. Inspired by everyday sounds of craftsmen from his hometown, Albano Laziale, the contemporary composer Battistelli created a score that has been performed around the world since its debut in 1981. What makes it so unique is the fact that except for the percussionist, all "musicians" are true artisans. They are exactly the ones whose work forms the basis of the composition. Yes, Experimentum Mundi is performed by bricklayers, cobblers, blacksmiths, stonemasons, barrel-builders, pasta makers. In Battistelli’s unparalleled opera (“opera” being the plural of opus – Latin for work) the performers work. Literally, on stage and throughout the performance. In this opera, to work is to play; to play music based on the insistent rhythm of the sounds of traditional craftsmen at work. The remarkable thing is that it works so powerfully and so convincingly. Critics agree, Experimentum Mundi is, without doubt, high calibre music. It is also a celebration of the accidental music produced by men working with skills that are fast disappearing.
