Birmingham Contemporary Music Group, CBSO Centre, Birmingham

Tokyo composer turned American has style that looks medieval but sounds modern

This latest BCMG concert had its pleasures; and it had its irritations. Among the pleasures was a pair of works, one of them newly commissioned, by the under-performed Japanese composer Jo Kondo. The irritations were of the BBC variety: long pauses between short works while technicians in headphones faffed around with microphones and music stands, in sovereign disregard for the convenience of a large paying audience.

Mona Hatoum: Bunker, White Cube Mason's Yard

Blasted cityscapes from the Beirut-born conceptualist

The latest exhibition from Beirut-born, sometime Turner Prize-nominee Mona Hatoum – best known for sending a camera through her inner tubes and projecting the results – explores themes of displacement and geographical and political tension. I know this because since I signed up to review it a fortnight ago, invites and reminders concerning this exhibition "exploring themes of displacement and geographical and political tension" have been hitting my mailbox with hectoring insistence.

Arditti Quartet, Wigmore Hall

Two difficult British exile composers receive ardent championship

Being a composer of contemporary classical music is a treacherous business. It's about the only art form in which stylistic choices can still force a creator into permanent exile. Two composers who have fallen foul of the British house style in recent decades and have sought musical asylum in America and Europe, Brian Ferneyhough and James Clarke, were receiving an extremely rare London premiere of their new string quartets at the Wigmore Hall last night. And you could see why Britain had shown them the door.

Modern British Sculpture, Royal Academy

Not so much an overview, more a series of inspired connections

Austere, elegant, impressive. Edwin Lutyens’s Whitehall Cenotaph is a thing of beauty, a monument that embodies permanence in the face of all that is impermanent, and solidity in the face of all that is ephemeral. It’s an inspired decision to bring it indoors, for inside a hushed gallery, away from the rush of traffic and stripped of its flags and sculpted wreathes, Lutyens’s memorial can at last be properly admired as a work of art.

Birmingham Contemporary Music Group, CBSO Centre, Birmingham

A nostalgic evening of avant-garde music that harks back to the Seventies

The Birmingham Contemporary Music Group does star concerts, which fill (or nearly) the CBSO Centre; and they do old-fashioned New Music concerts, which don’t quite empty it, but leave one wondering who exactly – if anyone - some of the works being played are intended to reach. Their latest offering was of this latter kind. The performers came and went, the audience clapped politely, the electric keyboard went wrong, luckily near the start of Enno Poppe’s Salz, so that we didn’t have to hear too much of it twice. The instrumentalists, brilliant players as one knows, communed with some pretty impenetrable material, “explained” by programme notes rich in imagery and gobbledy-gook. It was like being back in the Seventies: even quite a nostalgic afternoon, in its way.

Kafka Fragments, Barbican Hall

A Modernist mystery becomes supple and elusive in the hands of Dawn Upshaw

A 70-minute song cycle for soprano and violin, the Kafka Fragments is the magnum opus (the irony of its miniature forms seems entirely deliberate) of György Kurtág, a composer known for the inscrutability of his music. His lines arrive at the ears fully armed, unwilling to surrender their meaning. A performance of the Fragments at the Tanglewood Music Festival in 2008 famously drove a musically literate audience from the room, so can Peter Sellars's staged interpretation really offer a more engaging experience? Up to a point.

theartsdesk Q&A: Composer James Dillon

As Glasgow awaits his epic new work, the controversial Scot sets the world to rights

Glaswegian James Dillon (b 1950) is one Britain's most critically acclaimed living composers. Early detours as a drunken and drug-taking wastrel gave way to what he calls "musical terrorism". By which he means his blistering career as one of the most intoxicating and uncompromising of the New Complexity school of composers. His music has won awards (an unprecedented three from the Royal Philharmonic Society) but few British establishment friends or commissions, which has forced him into almost permanent exile.

Shadow Catchers: Camera-less Photography, Victoria & Albert Museum

Five contemporary artists in unusual and entrancing photo exhibition

Camera-less photography isn’t, as some might think, a 20th-century invention, discovered by experimental Modernists such as Moholy-Nagy and Man Ray. Thomas Wedgwood, before the invention of the camera and at the very beginning of the 19th century, made paintings on glass and placed these in contact with pieces of paper and leather which had been rendered light sensitive with chemical treatments. Where the painted areas blocked the light, the image left its trace. Unfortunately, since Wedgwood lacked knowledge of how to fix the images, the results vanished almost as soon as they appeared.

The Country, Arcola Theatre

Atmospheric revival of Martin Crimp’s play about middle-class adultery

Adultery has had a good press recently. Websites such as meet-to-cheat.com, illicitencounters.com and lovinglinks.co.uk have been in the news, and statistics suggest that more of us are being unfaithful than ever before. But although adultery is a staple of farce and mainstream drama, there are few plays that deal with the subject with quite the unsettling ambiguity and disturbing depth that characterise Martin Crimp’s modernistic play, first performed in 2000 and now beautifully revived by the up-and-coming Amelia Nicholson.
