From the New York Review of Books:
Already while living in Berlin in 1915, Ball and Hennings had organized a series of antiwar literary evenings with the intention, they said, to provoke, perturb, bewilder, tease, tickle to death, and confuse the audience. In Zurich, Janco made cardboard masks reminiscent of the ones used in African rituals and Japanese theater, but also strikingly original. As Ball wrote in his journal, “The masks simply demanded that their wearers start to move in a tragic-absurd dance.” Patrons of the cabaret who came expecting to hear selections from the works of Voltaire and Turgenev or another balalaika orchestra were subjected instead to skits enacted by masked figures dressed in colorful costumes made from cardboard and poster paint who accompanied themselves with drums, pot covers, and frying pans as they recited poems that sounded like this:
Gadji beri bimba
Glandridi lauli lonni cadori
Gadjama bim beri glassala
Glandridi glassala tuffm Izimbrabim
Blassa galassasa tuffm Izimbrabim.
The noise from the stage was deafening. There was bedlam in the audience too. The performers behaved like new recruits simulating mental illness before a medical commission. In less than a month the cabaret, which at first had welcomed all modern tendencies in the arts and hoped to entertain and educate the customer, had turned into a theater of the absurd. That was the intention. “What we are celebrating,” Ball wrote in his diary, “is both buffoonery and a requiem mass.” The scandal spread.Lenin, who played chess with Tzara, wanted to know what Dada was all about.
