The river rises in the Langres Plateau France and flows north past Sedan (the head of navigation) and Charleville-Mézières into Belgium. It is joined by the Sambre river at Namur. From Namur the Meuse winds eastward skirting the Ardennes, passes Liège, and turns north. Then it forms part of the Belgian-Dutch border, except that at Maastricht the border is more westward. Inside the Netherlands it continues north along Venlo, then turns westward.
In the Netherlands, it merges with the Rhine into an extensive delta, eventually flowing into the North Sea via the Nieuwe Waterweg and the Hollands Diep.
Maas' first fascination with music was sparked by listening to the radio when he was young.
Maas first began producing records in the '80s, but his first record The final XS was not released until 1995.
Maas first became popular in mainstream dance music through his remix of Azzido Da Bass' Doom's Night, in the wake of this success he released Music For the Maases Volume 1, a mix album consisting of many of his previous tracks and remixes.
