This sequence of pieces, composed in the main by Jackson Mouldycliff, with additional interventions & modifications from Colin Potter & Phil Mouldycliff, was started back in 2019 but because of the Covid pandemic it was only recently completed. The work centres on loops, repetitions & recurrent elements of sound assembled by MPM to accompany a series of mixed-media drawings by Phil, which in turn, takes as its starting point, star charts, celestial globes, planetaria, orreries, armillary spheres, astrolabes & astronomical clocks. Each of the eleven pieces has a title taken from a particular type of celestial orbit.
