Photographer Yewn De Sume went to Paris to study, and while he was there he got fired up in the seething emotions surrounding betrayal between men and women. France is the land, after all, where murder isn't really murder if it is a crime passionnel. The women in Yewn's pictures carry bottles of brandy and carving knives behind their naked backs or sit cross-legged and fume behind a mop of hair. Who knows whether life inspired art on this one, but I'd be worried sick if my daughter was going out with him. Photographs of Betrayal is on between March 28 and April 10, in the Heineken Gallery at the Fringe Club. Things have changed a lot in Russia recently, not all of it for the best, not least in the arts. The Bolshoi descended into fractious bickering and the Red Army Chorus and Dance Ensemble now do gigs with Finnish spoof rockers the Leningrad Cowboys to make some hard currency. But for some, the freedom to perform as they want has been a huge improvement on an already excellent product. The Russian State Chorus, who play at the Cultural Centre on Sunday at 8pm, were founded in 1936, during the height of Stalin's purges. They sang the world premieres of some important works including Prokofiev's Alexander Nevsky and Shostakovich's Ten Choral Poems. They only began touring internationally 30 years later and the 45-strong mixed choir astounded wherever they went, singing a mixture of Russian classics and arrangements of folk songs. One critic who saw them perform as Soviet citizens, and then as Russians a few years later, said the show went from funereal to fun. The singing has maintained the same spine-tingling quality and even un-amplified, they have what he called 'the range of a cathedral organ'. Their programme includes 10 Russian folk songs, and a polka arranged by Rakhmaninov. It is far too late to get tickets for anything at the Film Festival if you haven't already, (actually it is too late about three days after the postal booking opens), but to make up for it, the organisers have put together a good exhibition at City Hall. One half is posters from all the films showing in the festival that you can't go to see, and the other is a glorious heap of memorabilia to go with the The Restless Breed series of films featuring Cantonese stars from the 1960s. There are stills from the films, introductions and photographs stars such as Siao Fong Fong, Tse Yin, Lui Kei and Bobo Fung. Better still, there are costumes from some of the movies on display, and even a huge case full of awards collected by our heroes and heroines, mainly Hong Kong Film Awards, but some foreign ones too. Someone has even lent their Silver Bear from the Berlin Film Festival. The exhibition runs until April 9 in City Hall Exhibition Hall.
