I participated in the Delian Suite Four last year. The project involved composing works for bassoon that are based on one of the paintings of Hieronymus Bosch. I composed a short piece for piano, cello and bassoon. It was performed in June, 2008 at Angoulême, France. Below is the link to the soundfile. (Please note, this is a computerised rendition. I don't have a live recording at this time. Also, the tuning is twelve tone equal temperament. It is not a microtonal piece.)
