Frances-Marie Uitti, composer/performer, pioneered a revolutionary dimension to the cello by transforming it for the first time into a polyphonic instrument capable of sustained chordal (two, three, and four-part) and intricate multivoiced writing. Using two bows in one hand, this invention permits contemporaneous cross accents, multiple timbres, contrasting 4-voiced dynamics, simultaneous legato/articulated playing, that her previous work with a curved bow couldn’t attain. György Kurtág, Luigi Nono, Giacinto Scelsi, Louis Andriessen, Jonathan Harvey, Richard Barrett, Sylvano Bussoti are among those who have used this technique in their works dedicated to her. Collaborating significantly over years with radicals Dick Raaijmakers, John Cage and Giacinto Scelsi, she has also worked closely with Iannis Xenakis, Elliott Carter, Brian Ferneyhough and countless composers from the new generation. She premeired cello concerti dedicated to her By Per Norgaard, Jonathan Harvey and gave the first performance of the cello concerto of William Jeths in 2000. Peter Nelson is writing a work for her with the Scottish Chamber Orchestra. Canadian composer Rodney Sharman is also composing a cello concerto for her. She collaborates with pianist Rolf Hind, classical pianist Alwin Bar, filmmakers Frank Scheffer and Frans Zwaartjes, avant-garde guitarist Elliott Sharp, accordionist Pauline Oliveros, DJ Scanner, DJ Low, and Stephen Vitiello and video master Ferenc van Damme. Her compositions can be heard on ECM records, Cryptogrammophone, JdKrecords, Seraphin, Etcetera, and BVHaast. Her performances can be heard on ECM records, Wergo, CRI, Mode, HatHut, Raretone, Cramps, JdK recordings, BVHaast, Etcetera and Cryptogramophone.
