Their process began with a familiar problem: what's the point of recording improvisation? How can the interrelation of live and electronic music create a sound that is evocative and seemingly ‘natural’, while using modern techniques of digital synthesis and processing?
For Eno, the solution was to record Tom playing one-take improvisations over fifteen days, capturing both the audio of the piano and the MIDI of his performance through a device called the Moog Piano Bar, in order to produce the music without disrupting the immediacy and spontaneity of the improvisation.
This unintentionally led to a simple dynamic: Tom improvised the notes and Eno improvised the sounds while the two were interacting and reacting, Tom hearing Eno’s sounds in the room and responding to them, Eno receiving Tom’s notes, reshaping them in a fluid, reciprocal loop.
