Annemie Osborne starts studying the cello at the ‘Conservatoire de Luxembourg' with Claude Giampellegrini at age 8, continues at the University of Leeds (U.K.) with Anna Shuttleworth and prepares and accomplishes her Master degree in the class of Jeroen Reuling at the ‘Koninklijk Conservatorium Brussel'. She has had the opportunity to deepen and nourrish her understanding and practice of the cello during various master classes with, amongst others, Claus Kanngiesser, Johannes Goritzki, François Guye, Lluis Claret and Istvan Varga. It is from the age of 16 that she discovers and develops an interest in Jazz, improvised music, and World Music. Since then she has continually been exploring the art of improvisation in many various musical settings and encounters. Initiated to Jazz by Gast Waltzing, Marc Demuth and André Klenes, she has more recently been following classes of free improvisation with Kris Defoort at the Royal Brussels Conservatory.

An essential inspiration to her music has also come from work and ideas in the area of music therapy, especially through her encounter with the work of Luxembourgish music therapist Martine Wallenborn and the Taka Tuka Ensemble, and during participation at a music therapy course at the ‘Bodenseeinstitut' in Bregenz (AU) in 2008/2009.

In May 2009 she participates at a concert with Kris Defoort, Nic Thys, Pierre Bernard and Geoffroy de Massure at the concert hall ‘Henry Le Boeuf ‘ at Bozar in Brussels – in the context of ‘film and music', to accompany the silent movie ‘L'Hirondelle et la mésange', Belgian film from the 1920s. Her current musical projects include «OakTree» and « Octet Red », as well as a collaboration with singer and pianist Mathilde Renault (folk-pop) and the Jazz project of Corean singer Jihye Lee and pianist Nicola Andrioli. Moreover, she currently plays in a chamber music project with Luxembourg pianist Françoise Tonteling and Luxembourg percussionist Michel Mootz. She also occasionally is invited to play as a replacement in Luxembourg Chamber Orchestra (OCL).
