Phéromone

The analogy is with the functioning of the eponymous insect hormones, which transmit messages to other insects at a distance. The audible messages of the three musicians transmit signals from one player to the next, with the audience hearing the interaction of the signals in 'surround sound'. This is particularly apt as the overall effect of the music is of a darkened environment full of animal calls, as unseen predators stalk small mechanical prey and flocks of metal birds perch in the tinfoil trees.
