Two improvisations by saxophonist Jean-Luc Guionnet & violinist Dan Warburton recorded in Paris & Melbourne parking garages 14 years apart, registering the behavior and characteristics of environmental and instrumental sound within these unique spaces, edited by Eric La Casa and Philip Samartzis as a 4-channel master by synchronizing two sets of independent stereo recordings.

A reissue of the 2002 Chloe label album, where Jean Luc Guionnet on alto saxophone, Dan Warburton on violin, and Eric La Casa on microphones use the ambiance of the Paris Pre Saint-Gervais metro station as the starting point for free improvisations, using their surrounding as inspiration while they record a most unusual album of urban sound and discourse.
