In 1916 the First World War was grinding Europe to mincemeat. A band of poets, painters and out-of-work dancers who had fled to Zürich gathered at a little bar called the Cabaret Voltaire. What they made came to be called ‘Dada’ — a word that means nothing, found by flipping a dictionary open at random.

Did logic drive us into war? Then we’ll make anti-logic. Did reason get people killed? Then we’ll make anti-reason. Is art sacred? Then Marcel Duchamp will buy a urinal, sign it with the fake name R. Mutt, and send it to a museum.

Dada lasted just 8 years, but left three gifts that changed art history: the readymade, photomontage, and absurdist humour. Without Dada there is no Andy Warhol, no Jenny Holzer, no Banksy, no meme culture — and none of those ‘deliberately terrible’ SoundCloud covers.
