La fabbrica illuminata

La fabbrica illuminata, for voice and four-track magnetic tape, was composed by Luigi Nono in 1964. The music on tape, recorded at the Studio di Fonologia Musicale of the RAI in Milan, was the result of the complex elaboration of audio materials from different sources: parts performed by the RAI choir of Milan, “thematic” improvisations sung by the mezzo-soprano Carla Henius, voices and noises from the Italsider plant in Genoa-Cornigliano, and synthesized sounds. Original audio sources Three versions by the author were identified in the RAI archives in Milan: Milan RAI Q6, 1964, analogue magnetic tape, 1 inch, 38 cm/s, quadraphonic, created by the author for performance with live voice; Milan RAI Q7, 1965, analogue magnetic tape, 1 inch, 38 cm/s, quadraphonic. With the soloist voice recorded3 ; Milan RAI E28, 196[5], analogue magnetic tape, 1⁄4 inch, 38 cm/s, monophonic.

The tapes are still in good condition and include a set of metadata pertinent to the content of the recordings. The preservative re-recording of the analogue document in digital format was carried out in the Audio laboratory of the RAI in Milan, together with the MIRAGE Laboratory. This restoration is tied to the basic document CLN 0002 in the Archive of Casa Ricordi in Milan, a digital conservative copy of the magnetic tape Q6 of the Archive of the Studio di Fonologia at the RAI in Milan. The restoration of the sound tracks of the work has been completed at the Audio Laboratories of the University of Udine (Gorizia campus)under the expert supervision of Angelo Orcalli and edited by Angelo Orcalli. This restored version was based on the original documents and is accompanied with a technical report.
