Today Hendrik Andriessen is primarily known as the composer of some magnificent works for the organ, a few choral works mainly performed by amateur choirs, and some masses for the Roman Catholic service. In reality, Andriessen was for many decades a driving force in the Netherlands, as a versatile composer, a performing musician, a much loved teacher, the author of articles and books on music, the director of the Conservatories of Ultrecht and The Hague, and finally as a professor of musicology at the Catholic Univeristy in Nijmegen. Within a time span of some seventy years he has written a large oeuvre of instrumental and vocal works, from symphonies to songs, from masses to operas, from chamber music to organ works. The Netherlands Symphony Orchestra is the symphonic orchestra of the Province of Overijssel. This orchestra from Enschede performs with passionate dedication and virtuosity, and its broad, varied, and always exciting programs have earned it a firm place in this region and beyond. With its employmen tof historical instruments instead of modern ones in the performance of classical works, the ensemble has distinguished itself both in its immediate environment, throughout the Netherlands, and in foreign countries as a unique cultural ambassador on behalf of the Province of Overijssel.
