The final recordings of Un Drame Musical Instantané with co-founder Bernard Vitet, compiling sessions from 1998 to 2000 with the Machiavel Quartet and guests including Baco Mourchid and Nem, blending free jazz, electroacoustic experimentation, and multimedia spontaneity into cinematic improvisations that showcase the ensemble's enduring commitment to collective creation and sonic innovation.

A retrospective spanning ten decades (1958-2018) celebrating Jean-Jacques Birgé's multifaceted career through compositions reflecting each era, blending archival recordings with new works through a remarkable ensemble of longtime collaborators, from brass and strings to electronics and voice; a sonic journey bridging past, present, and imagined futures with impressive orchestration and narrative.

Merging electronic experimentation with improvisational spontaneity, Jean-Jacques Birgé's synthesizers and Bernard Vitet's trumpet weave alongside Michèle Buirette's vocals and Hervé Legeay's guitar, constructing a dynamic and unpredictable sonic landscape that blurs the line between composition and free expression, expanding the possibilities of form and texture.
