Recorded a few days after the Ictus duo album Clangs of percussionist and label leader Andrea Centazzo and soprano saxophonist Steve Lacy, this 1977 release presents the joyfully sophisticated 1976 concert in Udine, Italy of the percussionist & saxophonist joined in a trio with double bassist Kent Carter, performing 5 improvisations including the 3-part "Tao" series.

Originally released on the Hat Hut label in 1979, this 2-CD set of saxophonist Steve Lacy's quintet with Steve Potts on saxophone, Irene Aebi on cello, voice & violin, Kent Carter on bass, and Oliver Johnson on drums, are heard live in two tour-de-force concerts, first at the 1977 Jazz Festival, in Willisau, Switzerland, then in 1978 at Jazz Au Totem in Paris, France.
