The Advent Fantasy was commissioned by Sebastian Thompson as part of his Angels of Creation series. Based on four Advent themes (Veni Emmanual, Hemlsley, Wachet Auf and Rorate Coeli), it could serve either as a voluntary after a large service or a concert piece. For more concise liturgical use, it is possible to omit bars 43 - 98 or to use smaller sections at certain points within a service.
