Improvisation V on "Birds, drums and signals" (Nicolaaskerk, Utrecht)

In the previous post I said that Birds, drums and signals was the result of improvisations, like in fact all my pieces. To close the circle, I often consider the composition which I wrote as a starting-point for new improvisations. In that way, the line between composition and improvisation becomes very thin, one might say -as Bruno Nettl did in his insightful article Thoughts on Improvisation in 1974- that they are different points of a continuum. The following video (recorded in March 2012, unfortunately without a view on the pedals) shows what the result may be of this approach.
