Chris Dercon, director of Tate Modern, takes the helm of Artsnight for the first episode of this new series on BBC World News. Chris asks why Berlin is the creative capital of Europe; a magnet for artists and musicians, with an expanding array of galleries, museums and public arts intuitions. He talks to iconoclast Ai Weiwei, who has recently opened a studio in the city, despite being unable to leave China. He explores the intriguing world of drone art and the pioneering work of the late Berlin-based artist Harun Farocki; and he commissions a new film about Nick Cave's formative years in West Berlin, when the city was burgeoning with creative talent prior to the fall of the Berlin wall.
