In 1977 I started an improvisatory ensemble. It was modeled after some of the then current jazz ensembles, except it did not have a drummer. Our "solo" sections turned into group free improvisation segments, piquing my interest in free improvisation, a trait which has continued ever since. For the ensemble, I wrote several tunes. During the summer, I used these tunes to create several piano pieces.
In recent years these improvisations have been written out and are now available in new editions.
