With his former ensemble Musicum Antiquum, he was a true pioneer in the early music scene, when he traveled around the globe in the 1960's and '70's. He only started composing in the 1980's, but at the present time, he is in his most productive stage in life. Even though he collects rave reviews from his compositions, as well as from audiences as from written press, he remains very subdued about his own work. He doensn't even like to call himself a composer, but rather a 'notes-notating diarist'. In his compositions, Janpieter Biesemans often takes other cultures as a starting point for his compositions. With this inspation, he is able to synthesize these cultures with his own, creating a very specific language every time again.
