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.

Eric La Casa and Jean Luc Guionnet recorded this conceptual work in Melbourne, Australia, combining different scales of time, space, & attention, with different working strategies to create a gallery installation, and this book & DVD package exploring the acoustic phenomenon of "standing waves" to engage with the physical relationship between sound and space.

Thomas Bonvalet takes the banjo into unusual territory with Jean-Luc Guionnet performing on the organ at the protestant temple of Bergerac, France, in a beautifully terrifying album recorded during the MONC cultural arts centre's festival of avant-garde culture in 2010.

Stepping away from the saxophone, composer/improviser Jean-Luc Guionnet presents two large compositions for the organ, each taking a single CD to explore the organ's border effects, resonances, natural saturations, all artefacts that sign the acoustic, analogic, digital, process.
