Brass Band Gloria Deï, the group that commissioned this work, has its roots in the Frisian town of Gerkesklooster (the Netherlands), where the settlement Wigerathorp used to be. In the 13th century, a monastery was erected here, named Jeruzalem. This inspired the composer to base the work on the well-known melodious hymn Jerusalem by Sir Hubert Parry. Gercke’s Overture – the monastery was built by order of landowner Gercke Harkema – is followed by a slow movement in which the founders of the monastery, The Monks of Claercamp, take shape through the Gregorian chant Veni creator spiritus. In the last movement, Monastery Jerusalem, the main theme develops in all its glory.
