Berlin is a collective from Antwerp founded by Bart Baele, Caroline Rochlitz and Yves Degryse. Bonanza is part of the Holocene series named after the current geological period. The first of Bonanza's authors, Bart Baele, graduated from De Theaterschool in Amsterdam in 2000 and worked initially as a set designer. The second, Yves Degryse studied at an acting studio in Antwerp. He worked with SKaGeN and Camp.Marius. Work on each instalment of the Holocene entails thorough analysis of the topic followed by the selecting of a medium/media to present the collected materials. The final effect combines a documentary show with a video installation. It is shown in theatres, at exhibitions and festivals.
