Nixon in China, Metropolitan Opera HD Live

Dark picture and sound blips can't obscure the mastery of John Adams's first opera

Metcentric New Yorkers tend to think an opera hasn’t achieved classic status until it arrives at their vast inner sanctum. Whereas other cities worldwide know that the inimitable Peter Sellars production of grand opera’s last masterpiece (to date) has become a virtual brand since its 1987 Houston premiere. John Adams's first, and biggest, opera was an obvious here-to-stay triumph at the Edinburgh Festival the following year, and its strengths become more apparent with the passing of time.

theartsdesk in Colombo: Where Music Matters as East Meets West

Sri Lanka is longer on great percussionists than conductors

For hundreds of years now the island currently known as Sri Lanka has had a thriving musical culture (or cultures, not to politicise the issue). There’s been folk music for as long as there’ve been folks. The various strata of society have refined their ceremonial music, be it sacred or profane. Each ethnic group in each part of the island has hived off its own sub-genres over the centuries. And in the colonial era (eras) a whole new batch of influences arrived, fully formed, ready to be adopted wholesale or adapted and integrated for local use.

Imagine: Ai Weiwei - Without Fear or Favour, BBC One

Imagine a China where artists are unrestrained

If you found yourself thinking that you were watching Mission: Impossible rather than Imagine, you could have been forgiven. Alan Yentob had clearly been banned from meeting Ai Weiwei in China, and so one of their interviews was conducted over a webcam, with Yentob sitting in the dark, like some spymaster of the arts.

Do modern choreographers actively want to entertain us?

How do young modern choreographers engage with their audience? With references from the street - motion that the audience knows and recognises? With musical expressiveness? With the development of a technical style that has a language of its own? How about with an instinct, a yearning to entertain? Surely not!

When will it end? Dust continues to spoil fun for visitors to Tate Modern

Three days after its closure, and just a few days after opening, Tate Modern is still to make an announcement over the future of Ai Weiwei's interactive Turbine Hall installation. Will the closure of the dust-emitting artwork be permanent? Or are the Tate perhaps thinking of issuing dust masks to the public, which may, in fact, add a thrilling "danger zone" dimension to the experience?

It may be remembered that Tate Modern faced similar fears when it opened a decade ago. With the high number of visitors, it was suggested that the untreated wooden floors were creating enough dust to cause long-term damage to the paintings. But health and safety fears have also dogged previous Turbine Hall commissions:  in 2006, injuries were reported from visitors hurtling down Carsten Höller's slide (see below) and the following year people were tripping over Doris Salcedo's 167-metre floor crack.

Contemporary art lovers may like their art to be edgy and dangerous. But just how dangerous?

Minimalist installation speaks volumes at Tate Modern

One is so used to encountering spectacle in the Turbine Hall that visitors may feel distinctly underwhelmed by Ai Weiwei's minimal installation, the 11th Unilever Commission at Tate Modern. There appears at first to be nothing at all to see: the work, which resembles a huge blanket of ash by the time you reach the stairs to the bridge, is the same colour as the surrounding pale grey walls.

Gay porn, Chinese stasis, Serbian drama, Brit Monsters in teeming filmfest

It had to happen. Until now, I've always resisted. But last Thursday, I had, finally, to tear open the plastic container to get to the protection inside. A nice man from Screen International gave me his before leaving - he'd have no use for it. He added that he wouldn't have handed it over had it been stamped with the festival rubric; you know, something that would make it a keepsake.

City of Life and Death

A Chinese war film of symphonic ambition humanises the Japanese enemy too

From The Bridge on the River Kwai onwards, the Japanese haven’t tended to come up smelling of roses in war movies. Kind of unsurprisingly. In recent years it was Clint Eastwood who moved the story on. In Flags of Our Fathers he painted the Japanese military as the yellow peril, but gave them the benefit of the doubt in Letters from Iwo Jima, the other half of his Pacific diptych. City of Life and Death attempts to do in one film what Eastwood split into two: a portrait of the Japanese war machine as a manifestation of pitiless amorality; and the component parts of that machine as sentient human beings (at least some of them, anyway).
