Razen is a Belgian improvisational group that creates music informed by early music, the unique acoustics of sacred spaces and a deep sense of ritual and connection. The group's core members, Brecht Ameel and Kim Delcour, have been involved in this project for more than ten years and they join us here for an interview about their creative process, the importance of acoustics and how they incorporate the pipe organ's complex historical context into their sound.
