Annette Kruisbrink of Zwolle, the Netherlands, wrote this piece some years ago. It has been (most excellently!) recorded by Het Consort and Maestro Timmermann. It is a fantastic piece, one of the very best of the original 20th-century compositions that is available to us. The PMO has just posted our performance of "Dreamtime" from December 9th, Arts in the Village Series, Rehoboth, MA.
