In 1999, Alfa Centauri organised an “in between” event: the “Promo festival”. Featuring performances of Ron Boots & Friends, Syndromeda, Gert Emmens, Free System Projekt and Wave World.
Here is a small batch of pictures of the Wave World performance. Wave World is Harry Kessels and Gert van Santen. At that time Rolf van Slooten was also involved in the Wave World project, he created the stunning visuals.
