How Joe Tilson’s dazzling, graphic artworks captured the ‘white heat’ of technology - Christie’s

Sarah Kane revolutionised British theatre with five provocative plays written between 1995 and 1999. Her final work, 4.48 Psychosis, was her most personal, confronting the clinical depression she struggled with for years. The play was first performed posthumously in 2000, after she died by suicide in 1999. The Royal Opera and Guildhall School of Music and Drama commissioned Philip Venables to adapt the play as an opera, which debuted in 2016. The composer, also known for a certain “in-yer-face” approach, set Kane’s original text almost entirely, realising its 24 disjointed sections in a raw, imaginative score teeming with minimalist licks, prickly synth-pop and consoling nods to the baroque. The libretto shifts between poetic abstraction and scathing exchanges between a patient and a psychologist. An ensemble of six female singers navigates themes of depression, isolation and the agonising choices surrounding medication. One fractured personality … Sophia Burgos, Veena Akama-Makia, Hannah Edmunds and Jacquelyn Stucker in 4.48 Psychosis.

Ella Fleck at Ehrlich SteinbergThe raised platform in the middle of British artist Ella Fleck’s installation vibrates under your feet to the sound of a male voice. He’s whispering sweet nothings, intoning sexual fantasies. It’s all based on third-party agencies that manage OnlyFans accounts, interacting with users, creating fictional relationships that horny guys spend thousands on. It’s a greasy, gross, uncomfortable exploration of sex work on an industrial scale. Yuli Serfaty at Xxijra HiiYuli Serfaty’s headless metallic dog sculptures guard this booth, their claws sharp, their heavy teats dragging on the floor. It’s a surreal symbol of femininity pushed to an extreme, a body devalued and exploited. A video shows the creature trying to escape the booth, and succeeding. The whole installation looks like HR Giger meets Wolfenstein 3D, but with a nasty, satirical edge.
