Over the course of 2020 a new music festival was developed within the walls of the 800-year old Grand Commandery in Bilzen (B) commissioned by the Flemish Government.

​INTRA MUROS FESTIVAL FOR EARLY MUSIC – ALDEN BIESEN CASTLE is the full name of this annual international music festival that is built on three pillars: young talent - current international top quality - exclusive programs.

​Every year, a 'carte blanche' is given to a young Flemish musician: someone who is at the forefront of an international career is given the opportunity at the IMF to show him or herself as a 'musician in residence' during the entire festival weekend in various settings: solo, in chamber music and in combination with one of the guest ensembles or orchestras. For the first edition of IMF, this will be none other than Lise Vandersmissen, a young harpist from Bilzen, who is now particularly active internationally after training in Leuven and London.

​IMF also provides a platform for a (new) Flemish top ensemble that will come forth with an exclusive program or a new CD production. Le Pavillon de Musique, a brand new ensemble led by maestra Ann Cnop will bring the world premiere as well as the CD presentation of the violin concertos of H.-J. De Croes.

​In addition, there are of course internationally established names from Italy, Germany, the Netherlands and Poland, each time with exclusively curated programs for the Intra Muros Festival.
