The music under rusty records: restoring Risset's Duo for One Pianist

In the past few decades, electroacoustic music has taken up an important place in the musical landscape. From synthesisers to generative music systems, there exists a wide variety in the field. However, as time progresses, we are confronted with the question on how to preserve these artworks for the future. In this paper we describe the problems of preservation through a case study: Jean-Claude Risset's Duo for One Pianist from 1989. Finally we give a first account on the solutions found.
