Jan Caals studied at the Lemmens Institute in Leuven and at the conservatory of Brussels, where he graduated in solo singing and earned a higher degree to boot. He was a permanent core member of the Capilla Flamenca from 1993 to 2006. Ever since, he has been gaining more prominence as a soloist. He collaborates on a regular basis with the Flemish Opera, Il Fondamento, the Dutch Bach Society, the Philharmonia Hungarica, The Taiwan Symphony Orchestra, and Le Parlement de Musique. His repertoire ranges across a wide gamut from polyphony to contemporary music. He participated in many recordings, including a series of ten CDs with a survey of Flemish polyphony.
