The Mona Lisa has survived for more than 500 years, and an international commission convened in 1952 noted that "the picture is in a remarkable state of preservation."[44] This is partly due to the result of a variety of conservation treatments the painting has undergone. A detailed analysis in 1933 by Madame de Gironde revealed that earlier restorers had "acted with a great deal of restraint."[44] Nevertheless, applications of varnish made to the painting had darkened even by the end of the 16th century, and an aggressive 1809 cleaning and revarnishing removed some of the uppermost portion of the paint layer, resulting in a washed-out appearance to the face of the figure. Despite the treatments, the Mona Lisa has been well cared for throughout its history, and although the panel's warping caused the curators "some worry",[45] the 2004–05 conservation team was optimistic about the future of the work.[44]

I explore physical landscapes through sound, re-interpreting and re-imagining, using techniques of field recordings, assemblage, found objects, digital processes and improvisation.

The improvisations are a continuous landscape of noise impressions.
