Brian Eno – Compact Forest Proposal

Subtitled: 5 Studies for "010101", San Francisco Museum of Modern Art, 2001
I believe this was limited to 1000 copies.
Released in jewel case with clear tray and 2-page card.
From the CD notes:

There are 10 active CD players in this installation. Each is playing a specially cut CD, a single layer of the total music. The CDs have different numbers of tracks, some of which are silent, and each player is set to play these tracks in random order. The final music is therefore an ever-changing combination, unlikely to exactly repeat itself in any individual user's experience.

The studies on the CD represent possible conditions of the installation piece (i.e. conditions that it might randomise itself into sometime during the several months that it will play), although there are some elements in the studies that were not finally used in the installation itself.

My other installation pieces to date have been relatively "steady state" in that they've remained faithful to a specific harmonic palette. In this piece, however, one of the 10 playing CDs carries two quite different harmonic sub-strata. Since these are different tracks on the same single CD, they are never heard together, but alternate with each other. The other elements of the piece float over these backdrops: it's as though the weather changes.
