In Rysum in East Frisia a particularly valuable historical organ has been preserved: This unique instrument from the years 1442 and 1513 still has most of its original pipes. The organist Lorenzo Ghielmi and the Ensemble Biscantores present here a kind of organ mass in which organ pieces and liturgical chant alternate according to the practice of the time. The Italian organist and harpsichordist, Lorenzo Ghielmi, is organist on the Ahrend organ (1991) at the Basilica di San Simpliciano in Milan, where he performed from 1992 to 1994 the complete organ works of J.S. Bach. He gives concerts throughout Europe, Japan and the USA as an organist and harpsichordist. He has made many radio and studio recordings. He plays with his instrumental ensemble La Divina Armonia and in duet with his younger brother Vittorio Ghielmi (viola da gamba and harpsichord). In France, he received the Diapason d’Or for his recordings of Bruhns and Bach. He also played organ & harpsichord in the first recordings of Il Giardino Armonico. Lorenzo Ghielmi, teaches organ, harpsichord and early music at the Milan Accademia Internazionale della Musica.
