Plans for the 2026 Venice Biennale, which have been left in limbo by the sudden death of curator Koyo Kouoh, will be presented on Tuesday May 27.

A spokeswoman for the event told HENI News the Biennale's President, Pietrangelo Buttafuoco, will speak about "how the institution intends to move forwards".

Kouoh, who died aged 57 on Saturday, had been due to announce next year's theme in Venice on Tuesday May 20.

It is unclear if organisers will find an understudy to carry on her work or bring in a new curator.

Investment banker and art collector Artur Walther has given his huge photograpy collection to New York's Metropolitan Museum of Art.

The gift, described by the museum as "one of the most distinguished private collections of photography in the world", includes around 6,500 works from around the world with images from China, Japan and Africa particularly well-represented.

Among the artists and photographers whose work is included are Seydou Keïta and Samuel Fosso whose images will go on show in the museum's Michael C. Rockefeller Wing when it reopens this month.

The collection also includes photographs by South African Lebohang Kganye, Chinese artists Ai Weiwei and Hai Bo as well as Daido Moriyama and Nobuyoshi Araki from Japan.

Art collective For Freedoms has defended its plans to contribute artwork to a controversial prison project in New York.

The group, founded by artists including Hank Willis Thomas and Michelle Woo, is known for its political campaigning.

Documents seen by the website Hyperallergic show For Freedoms were approached to work on a site in Brooklyn by the Borough-Based Jails (BBJ) project which aims to build four smaller jails to replace the notorious Rikers Island facility.

Several artists have refused to take part but For Freedoms said its proposals, which include an oral history with testimony from people in custody as well as those working in the jail, had "prioritized ensuring that this work serves people in custody, and our negotiations continue to be guided by this shared commitment".

The Milwaukee Art Museum is looking for a new director after its current chief, Marcelle Polednik, announced she will step down in July.

Polednik spent nearly a decade in the role adding more 3,100 works to its permanent collection with recent acquisitions including paintings by Hale Woodruff and Christy Matson.

She recently secured a $5 million gift from local philanthropists Joe and Ellen Checota which means the Santiago Calatrava-designed institution could drop its admission charge.

Japanese-born artist Yasunao Tone, whose experiments with sound and music led Yoko Ono to describe him as a "Martian", has died aged 90.

Tone, who moved to the US in 1972, worked with artists including Nam June Paik and Merce Cunningham and was also associated with the Fluxus movement.

His experimental approach to music included scratching CDs and corrupting audio files to produce white noise and throwing random objects onto the strings of an open piano while recording the results.

Speaking about him to the Wall Street Journal, Ono said he had "totally destroyed" the usual notions of Asian music, adding: "He is not Asian. He is Martian.”
