The duo of bassist Jean-Jacques Avenel and alto saxophonist Daunik Lazro are captured live in 1980 at the Massy Library in France in an essential document of French free music, a marvel of liberated improvisation where Lazro's uncompromising voice meets Avenel's inspired and multifaceted playing, captured with clarity by engineer Jean-Marc Foussat in a performance both intense and deeply authentic.

Referencing the collective NY Loft scene of the 1980's, the trio of Jean-Jacques Avenel on bass, Siegfried Kessler on piano, keys & ring modulator and Daunik Lazro on alto sax & tuba sax, are heard in a Béziers Jazz Action concert recorded in the crypt of a Franciscan theater, in two suites of collective improvisation, the 2nd adding unusual electronics from Kessler.
