Eric Sleichim studied in Brussels and Liège. In the 1980s, together with Thierry De Mey, Peter Vermeersch and Walter Hus, he founded Maximalist!, with which he wrote music to the choreographies of Rosas and Ultima Vez. In 1988, he founded BL!NDMAN, a saxophone quartet with a traditional line-up that developed new playing techniques and considerably expanded the repertoire for the instrument, ranging from the beginning of this century as far as early music.
In addition to music for dance performances he also composed for theatre, performance, film and exhibitions, both with Belgian and foreign artists. In 2011, in collaboration with Muziektheater Transparant, Sleichim produced Utopia ::47 – a very last Passion.
The incorporating of electronics in his compositions heralded an era of extended line-ups: sax, strings, brass, drums and a line-up with voice, cello, tuba, turntable, saxophone and electronics. Since the opening of the Antwerp museum of fine arts MAS, Sleichim is its composer-in-residence.
