The Caecilia-Concert has performed in many configurations over the years. The core group, which for the first six years also included cornettist Fiona Russell, is often augmented by other leading players from today’s early music scene. Violinists Bjarte Eike, Enrico Gatti, and Veronika Skuplik, cornetto players Bruce Dickey, Jamie Savan, and Adrien Mabire, trombonist Simen Van Mechelen and organist David Van Bowel are among those who have been a part of the sound of the Caecilia-Concert and contributed to the success of the ensemble.
