“Oh yes, there is a metre, slightly irregular on one level but very regular on another. There are so many irregular things in this piece that at one point you need to have a regular metre as you say – a bass and a regular pulse anyway – but also a series of harmonies which are all symmetrical. The harmony always gives this impression of something followed by its inverse; there is always a centre – an axis of symmetry. This symmetry of harmony corresponds in harmonic terms to a regular metre. This is very important. There are three types of time. That which is chaotic and irregular such as you have in the beginning (in the speed I mean). Then you have, in the speed, the very regular rapid repeated notes – always in semiquavers. Finally at the end there is a regularity, a kind of metre – but with much ornamentation. The ornamentation is in fact very irregular, but the metre itself is very regular”. Pierre Boulez

“The aesthetics of man-made objects in space, their appearance and especially their orbits are transformed into a minimal audiovisual performance, showing the poetic dance satellites and their trash perform while revolving around us. Seemingly chaotic paths mutate to amazing patterns of an almost organic nature—all of it due to pure physical necessity. When we started working with global satellite data, their information was based on a website maintained by the US Air Force. Yet after some time, based on information from the Union of Concerned Scientists, we discovered that some objects were missing. Fortunately the data on classified satellites is generated by enthusiastic amateur astronomers observing the night skies.” Quadrature
