Beautiful contemporary dance from Scarlett and Maliphant, plus behind-the-scenes insights

What I want to know is: has there been a major upsurge in boys taking contemporary dance classes this year? And if not, why not? With the amount of male dancing in the media these days, the excuse that boys lack dancing role models just won't wash any more.

Orfeo, Royal Opera, Roundhouse

ORFEO, ROYAL OPERA, ROUNDHOUSE Austerely beautiful retelling of mythic Orpheus's grief and trials, with sounds to match

Austerely beautiful retelling of mythic Orpheus's grief and trials, with sounds to match

It’s quite a distance from the first performance of Monteverdi’s operatic cornucopia under the Mantuan Gonzagas’ imperious eye to this democratic celebration at the Roundhouse – 408 years, to be precise. Michael Boyd’s production takes us back even further, to those ancient Greek festivals of poetry and music which inspired the intellectual Florentines to fashion the art of opera in the late 16th century.

Kylie, iTunes Festival, Roundhouse

KYLIE, ITUNES FESTIVAL, ROUNDHOUSE The voice is thin, the music naff and terrible - but do give us the glitter and sparkle

The voice is thin, the music naff and terrible - but do give us the glitter and sparkle

Does Kylie exist without spectacle? Take away the 6ft headgear, the sparkly hotpants, the spangly corsets, the team of super-fit dancers dressed like futuristic liquorice allsorts, and what’s left? If you find whatever it is, please let me know. 

Mary J Blige, iTunes Festival, Roundhouse

MARY J BLIGE, iTUNES FESTIVAL, ROUNDHOUSE Powerhouse performance from the R&B superstar

Powerhouse performance from the R&B superstar

Trailing a string of Grammys and multi-platinum albums, and now a successful actress and purveyor of her own "My Life" perfume for good measure, you wouldn't think R&B legend Blige had much left to prove. However, she evidently sees it differently, and she ripped through this compressed and streamlined Roundhouse set as if lives were at stake.

Elbow, Roundhouse

Guy Garvey's alt-rockers give the iTunes Festival a likeable but rather studio-neat set

Punctually, following a tension-building countdown, Elbow entered the blue-lit stage at London’s legendary Roundhouse, beers in hand, and gestured the 1500-strong audience into a mass toast. With his slight stoop, soft Manchester accent and wayward estate-agent appearance Guy Garvey’s frontman persona takes more from familiar folk Daddies like Loudon Wainwright III than from the styled superstars also headlining at the iTunes Festival.

Kasabian, Roundhouse

Bloke rockers prove unexpectedly sensitive in a danceable, couple-friendly gig

The genteel north London of the Roundhouse isn’t the obvious venue for a ladtronica and bloke rock band. Especially one that’s recently come from headlining Glastonbury and is used to open horizons, and sound systems more dangerously ramped-up than Primrose Hill house prices. By giving a performance that wowed an audience of mainly young couples, Kasabian showed a character and identity that’s more nuanced than the standard hairy bloke depiction allows.

Sinéad O'Connor, Roundhouse

SINÉAD O'CONNOR, ROUNDHOUSE Songs from the new album hold their own against the back catalogue

Songs from the new album hold their own against the back catalogue

The cover of her new album, I’m Not Bossy, I’m the Boss, has Sinéad O’Connor sporting a black wig and latex dominatrix dress, a glammed-up guitar wrapped in her arms. Well, at least she made the effort. On stage at the Roundhouse she launched her fine new album sans latex or hair, in black t-shirt and trousers, still the shaven-headed siren of unbidden passions and complicated yearnings.

FALLEN/SERPENT: BALLETBOYZ AT THE ROUNDHOUSE Visual treats but the music's a drag

Visual treats from Liam Scarlett and Russell Maliphant but the music's a drag

School’s out for summer, even Parliament is on recess, and the streets around my house are suddenly devoid of children, as families make for the hills (or at least the beach). It should be dead season for all but prommers (and the suffering residents of Edinburgh) but ballet in London has had the most extraordinary week of first-class acts, with the Mariinsky at the Royal Opera House, Sylvie Guillem and Russell Maliphant at the Coliseum, and now the BalletBoyz’ 10-strong troupe The Talent at the Roundhouse in Camden.

Conrad Shawcross: Timepiece, Roundhouse

CONRAD SHAWCROSS: TIMEPIECE, ROUNDHOUSE Order and logic take on poetic form in a thoughtful work inspired by time

Order and logic take on poetic form in a thoughtful work inspired by time

Last time I encountered a work by Conrad Shawcross, it made me feel sick. His kinetic light sculpture, Slow Arc Inside a Cube IV, occupied a room the size of a broom cupboard at the Hayward Gallery’s Light Show. Inside a dense metal cage on spindly legs was a metal armature on which a high-wattage bulb was fixed. It looped the air at speed and the room, which was marked by lines that warped one’s sense of perspective, appeared to shrink and expand at a dizzying rate, or perhaps as if you yourself were growing and shrinking.

The Knife, Roundhouse

THE KNIFE, ROUNDHOUSE Sweden’s art-dance electro-tricksters turn the idea of a live show inside out

Sweden’s art-dance electro-tricksters turn the idea of a live show inside out

Nine people are on stage. Male and female. None is singing. All are dancing. No instruments are being played. For a 20-minute, three-song segment of Swedish art-dance electro-tricksters The Knife’s London show the sound was of a live concert, but nothing else was. Then, for “Networking”, the stage emptied and the music continued. All that was left were lights beaming into the audience.
