Three inverted metal trashcans, with microphones hidden inside. Strategically placed beneath a steady stream of rain drops, from a cracked porch roof. Who composed this? Ask the rain.

Overall intensity is governed by passing showers of rain. Hypnotic, gravity powered rhythms appear indeterminant, polyphonically-decoupled and ever drifting..

From over fourteen hours of multitrack recordings, a thirty minute selection became the source for experimentation. Versions were processed and mixed using harmonic resonators, filters, multitap delay, tuned reverb and time dilation.
The recordings were also analysed & auto-transcribed, with the resulting pulse map performed by a trio of percussion robots, playing gongs, timpani and rototom. Performance transferred, from raindrops on metal, to aleatoric percussion on skin & steel.
