The Cabaret Voltaire

The movement had a home base: a cramped nightclub in Zurich where Hugo Ball, Emmy Hennings, and Tristan Tzara staged nightly performances designed to insult every artistic convention.

Performers appeared in absurd cardboard costumes, chanted sound poems made of pure noise, and banged on drums until the audience shouted back. Provoking the crowd into anger wasn't a side effect — it was the whole point. If people left offended, the night had worked.
