The Chemical Brothers have long had one of the most vital shows around. It’s a visual spectacular that can only be likened to peak-time Pink Floyd or Jean-Michel Jarre, yet precision-tooled, without the bombast of those acts. Their long-term visual designer, Adam Smith, is mostly responsible and now he’s shot a concert film of the electronic duo’s appearance at the Fuji Rock Festival in Japan last year. Smith has directed a few bits and bobs before, notably the BBC adaptation of Little Dorrit, and he’s the perfect choice to take the Chemical Brothers experience into the cinema.

London's Barbican Centre is 30 this year, and with a special Olympics subsidy boost as the world's eyes turn to the British capital this summer, it aims to be as lovely inside as it is famously unlovely outside. Film beauties Cate Blanchett and Juliette Binoche appear live on stage and theatre giants Pina Bausch, Philip Glass and Shakespeare are celebrated in a season of prominent internationalism. Peter Sellars, Toni Morrison, Yukio Ninagawa, Krzysztof Penderecki and Chick Corea are among many other world names invited to EC2 over the season.

The Western image of manga comes from the thick volumes of knicker-flashing schoolgirls and lurid s.f. teenage boys pore over, and the anime (cartoon films) which adapt them. Singaporean director Eric Khoo’s animated adaptation of five stories by Yoshihiro Tatsumi, framed by details from his graphic autobiography A Drifting Life, reveals a radically different medium.

Scotland’s Bill Wells is hard to pin down. Although ostensibly a jazz pianist, boundaries don’t concern him. He’s played with Aidan Moffat and Isobel Campbell. In 2009 he made the GOK album with Japan’s Tori Kudo (who records as Maher Shalal Hash Baz). Lemondale was made in Japan with a raft of collaborators that include Jim O’Rourke, Kudo and members of Tenniscoats.

It's understandable that people get put off leftfield dance music, given how much micro-genre delineation and dog-in-a-manger protectionism there can be in underground scenes. It can seem a shame sometimes, but then again, these are part and parcel of the fertile creativity and passion that exists around the music, so it's swings and roundabouts.

Is this the year that G&S became definitively chic again? The slow-burn effect of ENO's "Miller Mikado" and Mike Leigh's Topsy-Turvy now results in numerous fringe benefits. Sasha Regan's all-male Union Theatre regime has delivered its best yet - Iolanthe at Wilton's Music Hall, the most touching and funny show I've seen over the last 11 months - and now Charles Court Opera gives us more witty operetta-in-close-up with a cast of nine backed up by two pianos.

There’s no doubt that In the Realm of the Senses shocked and still shocks, but after watching this first-ever uncut UK release, it’s hard to figure out what shocks most: the sex, the equation of sex, obsession and death, that all this takes place in a sealed environment ruled by ritual, or whether it’s the revelation that Japanese society could produce a film so opposite to its perceived or received persona. It could also be the fact that it's based on a true story.

The star ballerina Sylvie Guillem was rehearsing in London when she heard about the cataclysmic Japanese earthquake last spring, and the devastating tsunami in its aftermath. It was an apocalyptic blow that she felt personally. Since her first visit there as a teenager, the internationally renowned dancer has been drawn back to Japan year after year, winning legions of friends and supporters, the culture’s aesthetic clarity and spareness influencing her taste, and complementing her own evolution from classical ballerina assoluta into contemporary dancer stupenda.

Edit, edit. Inside TeZukA there’s a charming, elliptical, hugely stylish piece begging to be sliced and trimmed into focus - just as the manga master Osamu Tezuka must have daily occupied himself with as he prepared his graphic cartoons. The visuals in Sidi Larbi Cherkaoui’s piece are spectacular video animations of Tezuka’s fastidiously drawn scenes, the kerpows and the Zen landscapes, Black Jack, the transfigured rabbit. If it does nothing else, this show should whet your appetite for manga.
