Roscoe Mitchell is among the most significant composers in the entire spectrum of contemporary music. His oeuvre as a whole is among the most original created both in the African-American field and more generally in the musical languages of abstract improvisation.

Born in Chicago in 1940, Roscoe Mitchell was among the initial protagonists of the Experimental Band, an ensemble conceived by Muhal Richard Abrams to explore new musical territories, an important nucleus of artists who would later give birth to the AACM (Association for the Advancement of Creative Musicians). In 1966 Mitchell recorded "Sound," a seminal record of a style that went beyond "new thing" jazz, giving new emphasis to elements such as multi-instrumentalism, the expressive role of timbre and silences, and the richness of dynamic contrasts. Mitchell plays alto sax, clarinet and percussion at the time; his aesthetic is indebted to Coltrane, but he is already looking elsewhere, toward new syntheses.
Impossible in a few lines to account for the saxophonist's many collaborations. Mention should be made of the duo with Anthony Braxton and Muhal Richard Abrams, the Creative Orchestra, and the groups Sound And Space Ensemble and The Note Factory.

Michele Rabbia was born in Turin in 1965. Since the 1990s he has established himself as one of the most creative drummers in Europe. He has played with Aires Tango, with Antonello Salis and Stefano Battaglia, Dominique Pifarely, in Michel Godard's trio and with several improvisation groups. He has performed alongside theater performers and writers, and has been invited by many festivals in Europe, the U.S., and China.
