Rob du Bois (28 May 1934 – 28 August 2013) was a Dutch composer, pianist, and jurist.
Rob (Robert Louis) du Bois was born in Amsterdam. His French ancestry can be seen from his name, and he maintained a sympathy for the French mentality and language (Vetter 1966). After graduating from the Vossius Gymnasium in Amsterdam he studied law at the Gemeentelijke Universiteit in the same city. He began studying music with Chris Rabé at the Volksmuziekschool, later taking piano lessons, initially with Hans Sachs, and later with T. Hart Nibbrig–de Graeff. He decided to become a composer after hearing two symphonies by Matthijs Vermeulen in 1949. As a composer he was self-taught, with influences especially from his contact during the 1950s with the composers Kees van Baaren and Daniel Ruyneman (Anon. 1999; Ramaer 2001a).
In 1959, Bois became associated with the group of composers formed around the Gaudeamus Foundation, of which he later became a board member (Anon. 1999). He first became known outside of Holland as a composer when his music was performed at the Zagreb Biennale and the Warsaw Autumn, in both 1967 and 1969, and at the Festival of the International Society for Contemporary Music in 1967 in Prague (Anon. 1973).
In the late 1960s, Bois became a performing member of the ICP (Instant Composers Pool), which had been founded in 1967 by saxophonist Willem Breuker, pianist Misha Mengelberg, and drummer Han Bennink (Whitehead 2002). It was for Breuker that du Bois composed the Breuker Concerto in 1967, a work for two clarinets, four saxophones, and 21 strings, which was premiered by Breuker with the Rotterdam Philharmonic Orchestra (Buzelin and Buzelin 1992, 43). Du Bois played keyboards in a number of ICP projects, including Breuker’s grandiose February 1969 “happening”, Mozart Opera, which also featured Derek Bailey on guitar, Paul Rutherford and Willem van Manen on trombones, and Han Bennink on drums (Buzelin and Buzelin 1992, 36). In 1972, du Bois alternated with Louis Andriessen in the ensemble that accompanied viola soloist Lodewijk de Boer in performances of Breuker's Speelplan for viola, seven instruments, and live electronics, the latter performed by Michel Waisvisz (Buzelin and Buzelin 1992, 44). Bois also participated in recordings of Breuker’s music—mostly incidental music for various theatre productions—by the ICP and other groups between 1968 and 1977. Some of these were released on LP in the early 1970s, and some others more recently on a CD on Breuker’s BVHaast label.
