International Composer Festival with Klas Torstensson

This year’s International Composer Festival is dedicated to the Swedish-Dutch composer Klas Torstensson.

Klas Torstensson’s music is powerful, with volcanic eruptions and, at times, a kind of hammering energy. But ever since his 1999 opera Expeditionen, a more lyrical, almost bleeding emotionality has begun to emerge. Torstensson’s music moves between extremes.

Born in Sweden in 1951, Klas Torstensson has lived in the Netherlands for more than fifty years – he moved there in 1973. An internationally acclaimed composer, the festival focuses primarily on his output from the past two decades, though music from the early 1970s is also featured. The result is a broad retrospective.

The Royal Stockholm Philharmonic Orchestra opens the festival, and, as is tradition, the Norrköping Symphony Orchestra also makes a guest appearance. Besides his own works, Torstensson has chosen to include music by Johann Sebastian Bach/Anton Webern and by Charles Ives – works that meant a great deal to him as a young man dreaming of becoming a composer.
