A monumental 8xCD box overview on Joëlle Léandre (born 12 September 1951 in Aix-en-Provence, France) a legendary double bassist, vocalist, and composer active in new music and free improvisation. A staggering, foundational body of work from one of the most radical and influencial avantgarde performer of the 20th century. In the field of contemporary music, she has performed with Pierre Boulez's Ensemble Inter Contemporain, and worked with Merce Cunningham and John Cage. Both Cage and Giacinto Scelsi have composed works specifically for her.  She gave an historic solo concert in "Jazz em Agosto" in 2007 (Calouste Gulbenkian Foundation, Lisbon, Portugal). In this same top jazz festival, Léandre performed also in the "Quartet Noir", a quartet with quite rare live performances, with Marilyn Crispell, Urs Leimgruber and Fritz Hauser.  She has also collaborated with some of the preeminent musicians in the fields of jazz and improvised music, including Derek Bailey, Barre Phillips, Anthony Braxton, George Lewis, India Cooke, Evan Parker, Irène Schweizer, Steve Lacy, Maggie Nicols, Fred Frith, Carlos Zingaro, John Zorn, Susie Ibarra, J. D. Parran, Kevin Norton, Eric Watson, Ernst Reijseger, Akosh S. and Sylvie Courvoisier.  In 1983 she became a member of the European Women Improvising Group (EWIG), which resulted from former Feminist Improvising Group and in later 1980s she co-founded the feminist improvising Trio Les Diaboliques, with Schweizer and Nicols.
