Lacus Flevo refers to the former Lake Flevo, a large inland water of centuries ago, which was located roughly where the Dutch province of Flevoland now lies. It was one of many lakes that were created at the end of the last ice age, after the retreat of the glaciers. In the first part of this concert work, the unspoiled nature of this lake from earlier times is atmospherically depicted. Throughout history, there have been various interventions to reclaim the land for agriculture and habitation – the Zuiderzee Works are the best known and most fundamental example. This complex set of projects led to the creation of the province of Flevoland, where Lake Flevo was once situated. This transition is depicted in the second movement of the composition, by a powerful theme that leads to a grand finale. This composition was written for the fortieth anniversary of the village Zeewolde in Flevoland, as well as the music society AMVZ, also celebrating its fortieth jubilee.
