Four free players from the assertive history of French free jazz--Jean Querlier on alto saxophone & soprano oboe, Jouk Minor on baritone & sopranino saxophones, Rachid Houari (the original drummer for Gong) on drums and Joseph Traindl on trombone--are heard in this exceptional and determined set performing two compositions by Jouk Minor at the 1st Massy Independent Festival in 1975.

Two suites recorded in 1978 from the French improvising quintet of Jouk Minor on baritone saxophone & contrabass clarinet, Josef Traindl on trombone, Jean Querlier on alto saxophone, Christian Lete on drums and Dominique Regef on hurdy gurdy, two journeys guided by waves of drone from Regef's hurdy-gurdy as each player emerges and subsides in billows and surges of collective expression.

This single extended performance brings together a collective of improvisers playing low range instruments in order to build an acoustic sonic sculpture, from the quintet of Daunik Lazro on baritone saxophone, Jouk Minor on contrabass sarrusophone, Thierry Madiot on bass trombone & telescopic tubes, and both David Chiesa and Louis-Michel Marion on 5-string double bass.
