This second chapter is recorded by a group of 18 improvisers with roots in jazz and classical music. The group investigates performing and improvising music, in close relation to the present time; what are the possibilities in playing music, when changes occur unnoticed? How do musicians relate to the running time of a performance? How does our hearing and memory react to these slow changes? As a result 'Vvolk' lets you experience music which is less perceived in the present time, but rather occurs in our memory of the past. This clearly challenges the improvising musicians, and makes audience and performers discover new territories in collective improvisation.
