Elektra, Gergiev, LSO, Barbican Hall

Felicity Palmer's Clytemnestra takes honours in a pulverising performance

Richard Strauss’s 1909 opera Elektra is a diabolical piece of work - less an opera than an event determined to cut its mark. A vast orchestra of 112 players unleashes a two-hour tsunami of sound across the stage, on which female voices are buffeted like pieces of driftwood, shrieking of mothers who murder husbands, daughters who want to murder mothers, rivers of blood, flayed horses, dogs, bodies. Subtle it isn’t. Loud it is. In the hands of Valery Gergiev and London Symphony Orchestra this week, pulverisingly loud.

Agon/ Sphinx/ Limen, Royal Ballet

What's new with the new McGregor? The music's good, for one thing

Extraordinary lives dancers lead at Covent Garden - in a single day rushing between studios to rehearse the tortured, introspective Mayerling, the pristine classicism of The Sleeping Beauty, the off-centre acrobatics of Balanchine’s Agon and the static wriggles and hip-snaps of Wayne McGregor. All of these works are currently in Royal Ballet repertory, and you can see Ed Watson, Yuhui Choe, Johan Kobborg and an array of others on stage at the moment in all or any of these. But at what cost to communicating hugely different styles of choreography?

theartsdesk in New York: Extreme Blake

William Blake marries heaven and hell at the Morgan Library, Manhattan

Outwardly the Morgan Library & Museum is a citadel of sedateness - inside it may be the locus of turbulence. Thirteen years ago I walked around one of the rooms with the actress Charlotte Gainsbourg, on whom I was writing a profile. She was then starring in Franco Zeffirelli’s Jane Eyre, and it made sense for us to look at the Morgan’s exhibition of Brontë juvenilia together. She seemed vaguely haunted by the show; I know I was.

Titian's Bacchus and Ariadne

A young man's masterpiece

In 1519 Titian was commissioned by Alfonso d’Este, the famously irascible Duke of Ferrara, to provide the first of three paintings for a study, the so-called camerino d’alabastro or alabaster room. If the following five years of delays and procrastination drove the duke almost  to distraction, they produced what is arguably the most famous room in the history of Western art.
