Joris Verdin is both organist and musicologist. This combination is the reason for his preference of reviving forgotten music at the same time as he creates contemporary compositions. He has recorded over forty CDs as a soloist, spanning many musical eras and styles. After various activities as accompanist, arranger and producer he now focuses on the organ as well as the harmonium and has become internationally reputed as a specialist. He teaches the organ at the Royal Conservatory of Antwerp and is professor at the University of Leuven, Belgium.

Master classes, musical editions and articles are an important part of his activities. Amongst them, the first complete edition of César Franck harmonium works and the first handbook of harmonium technique.
