The art of indexing: quantifying creativity in the financial world - Art Basel

The literary power couple is a historically seductive concept. Two writers sharing a life, their private and creative worlds entwined, each becoming witness to and critic of the other’s work. Think Simone de Beauvoir and Jean-Paul Sartre, Joan Didion and John Gregory Dunne. Or, less auspiciously, Sylvia Plath and Ted Hughes. Now, into this illustrious company steps a new pair: the novelist Marlon James and the biographer Nicholas Boggs, whose books have each been shortlisted for one of Britain’s most prestigious literary awards – James for the Booker prize and Boggs for the Baillie Gifford prize for nonfiction. Between them, they have produced two formidable books, each the culmination of years of work, and each concerned with the lives of Black queer men whose stories have often been overlooked. “I’m not sure what to do with it,” James says, when I ask how they feel about the inevitable impending “literary power couple” label. “I have all these romantic notions that we were like Joan Didion and John Gregory Dunne or something – I don’t know. What do you think?” He turns to Boggs, who laughs. “It’s all very new,” he says.

A fitting tribute to the late star’s breakout album 20 years after its release, this special concert was held at the Roundhouse in north London earlier this week. It’s led by a team close to Winehouse’s music, including the album’s producers Mark Ronson and Salaam Remi, and features the Amy Winehouse Band playing all the hits including Valerie and Rehab. Special guests include Corinne Bailey Rae, Flo, Jessie Reyez and Jorja Smith.

Siobhán McSweeney is teaching me her preferred way to enjoy a packet of cheese and onion crisps. She has arranged two matching slabs of Cadbury’s Dairy Milk chocolate, two piles of Tayto crisps and two cans of Guinness on the table in front of us – and is issuing strict instructions. “Don’t swallow!” she booms theatrically, and I freeze, my mouth full of Taytos. The trick, McSweeney explains, is to get the crisps, chocolate and Guinness into your mouth at the same time, and then swill it all around a bit to make a kind of boozy, oniony soup. “See?” McSweeney is watching me carefully to check I am putting all the ingredients into my mouth in the correct order. “It’s delicious! Just delicious!”McSweeney burst into the public consciousness back in 2018 with Derry Girls, a comedy series about a group of Catholic schoolgirls, set against the background of the Troubles in 1990s Northern Ireland. McSweeney won a Bafta playing the girls’ headmistress, Sister Michael – a potty-mouthed, judo-loving nun – and can count Martin Scorsese as a fan.
