Yoko Ono at 4 A.M.

Before sunrise this past Sunday morning, the Museum of Modern Art invited seven museums around the world—in time zones stretching from Sydney to Los Angeles—to celebrate the 50th anniversary of Yoko Ono‘s Morning Piece. The work, included in Yoko Ono: One Woman Show, 1960-1971, was performed on Ono’s rooftop in New York as a tribute to fellow Fluxus artist George Maciunas in 1965. On Sunday, more than one thousand viewers got out of bed extra early to join Ono at MoMA in celebration of the summer solstice. Dancing to Fela Kuti and helped along by friends including fashion designer Virgil Abloh, musician Blood Orange and a mix of the art world and downtown set, Ono howled as the sun rose. By restaging it for 24 hours (and at MoMA from 4-8 a.m.), Ono sought to make good on her original instruction for her early work: “Since there is no country without a morning, you can use it anywhere you go.”

“Yoko Ono: One Woman Show,” is on view at MoMA through September 7, 2015.
