How Martha Graham's 'Rite of Spring' imposed order on chaos

Stravinsky's "Rite of Spring" is famously chaotic, making it an odd choice for Graham's highly precise style. Her 1984 choreography for it, however, redefined how people saw the ballet's score. Graham's version is still performed today; below is an excerpt from a 2018 performance by the Paris Opera.

Disillusioned mid-century playwrights, such as Samuel Beckett and Eugène Ionesco, brought existentialist ideas to the stage through the Theater of the Absurd.

Samuel Beckett's 'Waiting for Godot' dramatizes existential absurdity

The play, originally staged in 1953, is notorious for its lack of action. For the most part, its two principal characters, Vladimir and Estragon, spend the majority of the play wondering whether a mysterious Godot will ever appear. By the end, Godot has still not arrived, yet Vladimir and Estragon do not move, a choice that reflects the existential notion that humans often hope in vain for meaning that does not exist.

Warhol was on the cutting edge of many art forms, and performance art was no exception.

Performance art depends on the actions of the artist

Part theater, part anarchy, part absurdism, performance art encompasses a whole range of media and genres. The short version is that it’s conceptual, often spontaneous art that is performed live. Performance art is inherently confrontational, challenging societal ideas of what constitutes “fine art,” making it an ideal vehicle for political and protest pieces. It’s closely related to other avant-garde movements like Dada and Futurism.

‘The Artist Is Present’ was inspired by an earlier performance titled ‘Nightsea Crossing’

In the ‘80s, partners Abramović and Ulay sat across from each other in public without moving or speaking. Ulay was unable to continue after a certain point, but Abramović kept going. “The Artist Is Present” marked Abramović continuing the performance without him.

Performance art differs from other performances, like dance and theater

While performance art is a very flexible genre, it is defined by several core elements: time, space, the body, and the relationship between the artist and the audience. These elements may be manipulated in infinite ways to convey the artist’s message, such as how endurance performances challenge the limits of the body over long periods of time.

Arthur Russell's avant-garde music spanned many genres

The classically trained cellist moved to San Francisco in the early 1970s, mingling with the hippie movement and the Beat Generation. After arriving in New York in 1973, he began exploring the nascent punk and disco scenes, infusing them with his classical training; however, his eclectic style might've been part of the reason he never broke through during his lifetime. That variety, though, is what draws so many devoted listeners to his work today.

Zurich's Cabaret Voltaire was the epicenter of early performance art

In early 20th-century Zurich, one nightclub was the epicenter of avant-garde art and performance: Cabaret Voltaire. Night after night, crowds of artists, writers, philosophers, and others would gather to watch—or participate in—wild, unrehearsed performances that could include anything from sound poems to traditional folk dance. The atmosphere at Club Voltaire was the ideal breeding ground for outside art movements, and it is thought to be the birthplace of Dada, a precursor to performance art.
