Longplayer Assembly

24 leading thinkers converge in a non-stop 12-hour conversation relay, live online on Saturday 26 September, 10:00 – 22:00 BST.

The Longplayer Assembly marks the twentieth anniversary of Jem Finer’s Longplayer – a continuous piece of music commissioned by Artangel that began playing at the turn of the millennium, with a duration of 1000 years. Embracing the essence of Longplayer as a contemplation of time, the Longplayer Assembly echoes this continuity through its convergence of 24 participants, from around the world, whose individual specialist work embodies long term thought. Each speaker will converse in turn, passing the virtual baton every 30 minutes in a non-stop 12-hour live relay.

There is no formula for the conversations beyond the stipulations that they should last exactly 30 minutes, and should address themselves to a series of central questions: “What kind of future do you want and how could it be realised within your field of expertise?”, “What stories can you tell that point to the kind of future we could be heading towards?” and “Might collaboration between disciplines help to imagine positive long-term change?” – Claire Armitstead, the Guardian, 22 September 2020

Presented in association with London Review of Books. Supported by the Trinity Buoy Wharf Trust.

Akomfrah was a founding member of the influential Black Audio Film Collective, which started in London in 1982 alongside the artists David Lawson and Lina Gopaul, with whom he continues to collaborate. In 1986 their first film, Handsworth Songs explored the events surrounding the 1985 riots in Birmingham and London through a charged combination of archive footage, still photos, and newsreel. The film won several international prizes and established a multi-layered visual style that has become a recognisable motif of Akomfrah’s practice. His work Vertigo Sea was exhibited at the 2015 Venice Biennale, exploring what Ralph Waldo Emerson calls ‘the sublime seas’. His largest film installation Purple, exhibited at the Barbican in 2017, addresses climate change, human communities and the wilderness.
