Joss Stone is one of our most popular and successful soul singers, with a rich bronze voice and supple delivery that’s already earned her two Brit Awards and a Grammy, and made her Britain’s richest woman under 30. She burst onto the scene at the age of 16 with Soul Sessions, an acclaimed album of soul classics from artists including Arethra Franklin and Carla Thomas.

Eno Williams is lead singer and composer of the band Ibibio Sound Machine, an eclectic fusion in which contemporary dance and synth are laid over classic Nigerian highlife rhythm and vocals. The full line-up consists of eight musicians working with a range of influences, including Brazilian percussionist Anselmo Netto, Ghanaian guitarist Alfred Bannerman, and producer and saxophonist Max Grunhard.

Quentin Blake, illustrator, cartoonist and children’s author, has, to date, illustrated over 300 books. He is most famously associated with Roald Dahl, but he’s worked with a number of children’s writers, most recently David Walliams, illustrating the actor's debut novel The Boy in the Dress. He is a patron of The Big Draw which aims to get people of all ages drawing throughout the UK, and of The Nightingale Project, a charity that puts art into hospitals. Since 2006, he's produced work for several hospitals and mental health centres in London and in France.

How do you live a good life? Is wealth a good thing? How do you create a just society? The United Kingdom's electorate recently pondered such questions in the polling booth, and made their decision. The Labour Party is agonising over them as it chooses its next leader. And yet while these anxieties may feel very now, they have deep roots. According to the historian and broadcaster Bettany Hughes, such questions first crystallised in the minds of three thinkers, born within a century of one another 2,500 years ago, who are the subject of her new series.

Roger Rees, whose death at the age of 71 was announced yesterday, never intended to act. He trained at the Slade and made extra money painting theatrical scenery. One day a director asked if he’d like to act, and he laid down his brush. The second time he applied to join the RSC, he got in. He stayed with the company for a now unimaginable 22 years and in due course became one of the great stars of British theatre in the 1980s.

Last week the 15th International Tchaikovsky Competition in Moscow was rung down with a sigh of relief for the home team, with once again a Russian pianist in possession of the gold medal, Dmitry Masleev following 2011’s Daniil Trifonov. It was all very satisfactory for President Putin as he delivered his speech at the winners’ gala, being Tchaikovsky’s 175th anniversary year, but it was not a result that many disputed. The modest Siberian, 27, is a thoughtful pianist as well as a powerful one in traditional Russian manner.

If you’ve read any of the glowing reviews for the current revival of Caryl Churchill’s cloning play A Number, you’ll know all about the extraordinary set. Produced at the Nuffield in Southampton last year and transferred to the Young Vic this week, the intense production places father-and-son performers John and Lex Shrapnel inside a mirrored box where their every move is reflected infinitely. The audience is split into four around its edges, and watches the action through one-way glass. In between scenes, the mirror effect is reversed and the audience sees itself reflected.

Frank Sinatra is back in London in the centenary of his birth. His disembodied voice is returning in a show called Sinatra: The Man & His Music. At the London Palladium, where he made his British debut 65 years ago, there’s to be a 24-piece orchestra, 20 dancers and video effects galore in a multi-media concert featuring many of his best-loved songs. At the heart of it will be footage supplied by the Sinatra Estate. For those who never saw Sinatra live, the idea is that this will be the next best thing, at least since the last time he was exhumed.

Is there more than one Michael Longhurst? As sometimes happens in theatre, a rising young director seems to be everywhere at once. His calling card is the modestly universal Constellations. Directed with clarity and simplicity, Nick Payne’s romantic two-hander with multiple narratives has travelled from the Royal Court via the West End to New York, before touring the UK and heading back to London this week. Longhurst may need to clone himself in order to be in two places at once: his production of Caryl Churchill’s A Number is also opening at the Young Vic.

On paper, Richard Thompson's career seems every bit as exotic as one of his songs. At the age of 18 he helped found folk-rock pioneers, Fairport Convention. Later, in the Seventies, he and wife Linda recorded several successful records together before retreating to a Sufi Muslim commune. Then, after returning to music, Thompson relocated to LA, where he worked on a unique combination of British folk and virtuoso rock guitar that would make him, amongst connoisseurs, one of music's most acclaimed performers.
