B-Classic is a festival in and around the basilica of Tongeren. It began under the name Basilicaconcerten Tongeren and later adopted the names Basilica Festival van Vlaanderen and Festival van Vlaanderen – Limburg. The festival has been active for the past half-century. B-Classic is an international classical music festival as well as a social laboratory and an artistic breeding ground for musicians. It gives participating musicians the chance to evaluate, reconsider and develop their artistic practice. To that end, it uses its pressure cooking formula, in which musicians have to realise short-term artistic collaborations. B-Classic puts classical music in a contemporary context. It focuses on live experience and cross-pollination.
The festival is a branch of Flanders Festival (Festival van Vlaanderen).
