Two more contrasting pianists than Yuja Wang and Martin Helmchen would be hard to find. To move within 24 hours from the glittering assault of Wang’s technique to the restrained, almost introverted, Helmchen is an exercise in extremes, and one that left me yearning, Goldilocks-style, for a soloist neither too hot nor too cold, but just right. Dvořák’s Piano Concerto may have been a sober affair, but the London Philharmonic Orchestra and Vladimir Jurowski bid farewell to their Southbank season in a blaze of Central European passion and music by Suk and Janáček.

A new publicly funded UK web channel for performing arts opens tomorrow morning, preparing for a major launch this weekend streaming top international streetdancers to the web audience and publishing John Peel's notes on his record collection. The channel, called The Space, is funded by the Arts Council England in partnership with the BBC, and will run for six months over and through the Olympics period as an on-demand channel to put performance out via smartphones, tablets and computers.

How incredibly heartening that this latest edition of the BBC Symphony Orchestra's Total Immersion, focusing on the music of the contemporary Estonian composer, Arvo Pärt, sold out days in advance. Including an introduction to Pärt's music by the BBC Radio 3 presenter Sara Mohr-Pietsch, Dorian Supin's documentary film about the composer, 24 Preludes for a Fugue, a freestage event by the BBC SO Family Orchestra performing a new work inspired by Pärt's music, and three concerts, Saturday's day-long exploration provided an embarrassment of riches.

The full programme is announced today for the London 2012 Festival, from 21 June-9 September, celebrating the London 2012 Olympics and Paralympics.

Among more than 25,000 artists from all 204 participating nations, star names include theatre stars Cate Blanchett, Alan Ayckbourn, Mike Leigh and Julie Walters, musicians Damon Albarn, Daniel Barenboim, Gustavo Dudamel, Gilberto Gil, Zakir Hussain, Yoko Ono, Simon Rattle, Rihanna and Scissor Sisters, visual artists Ai Wei Wei, Tracey Emin, Damien Hirst and Anish Kapoor, and TV characters Stephen Fry, Wallace and Gromit and Dr Who.

If you’re game for a galling statistic, here’s one that’s guaranteed to stun: at present, only 14 per cent of British films released in the UK are directed by women. If that seems oddly as well as infuriatingly low, it’s probably because so many of the brightest and boldest British film-makers of recent years, from Lynne Ramsay to Lucy Walker, are women – women who it seems are exceptions as well as being exceptional. These towering talents, it could be said, give the impression that opportunities for women behind the camera are at a high, rather than being persistently paltry.
