Marc Grauwels is undoubtedly one of the Belgian flautists most catching the limelight today. His eclecticism as an international soloist has inspired a lot of composers from all over the world who wrote especially for him or associated him to the first performance of their creations. In this way, in 1985, he played in duo with the guitarist Guy Lukowski the first performance of the famous and well-known History of the Tango from Astor Piazzolla and he also participated to the first recording of this work. He also participated to the creation of the Cantate for Europe from Ennio Morricone. More recently, the Greek composer Yannis Markopoulos wrote for him his new concerto for flute that was played as one of the opening musics for the Olympic Games in Athens in 2004.
He made his orchestral debute, aged only nineteen, with the Flemish Opera. In 1976 he joined the Monnaie Theatre in Brussels as piccolo solo (the Belgian National Opera House) which he left to become first flute soloist in the Symphonic Orchestra of the Belgian radio and television. He participated in the recording of the sound track of the film Amadeus by Milos Forman and he interpreted the youth sonatas, the quartets and the concerto for flute and harp of the integral works of Mozart offered in a single box containing 170 CDs.
