If you weren’t already aware that the Guest Director of the 2012 Brighton Festival is acting royalty, the preponderance of fop fringes and artfully flung scarves at the Dome Concert Hall on Saturday night was a good clue. Vanessa Redgrave is the figurehead for this year’s reliably eclectic (if a little conceptually convoluted) programme. And judging by the opening Q&A, dotted with as many grassroots political activists as members of the Redgrave clan, she’s going to be a busy one.

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.

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.

Southbank Centre’s current season has included weekends devoted to three contemporary giants: Pierre Boulez, Conlon Nancarrow and George Benjamin. But it closes with a festival devoted to not to one contemporary composer but 20. The New Music 20x12 weekend, initiated by the PRS for Music Foundation, is a Olympic celebration of the range and diversity of new British composition. Indeed, the only thing all 20 pieces will have in common is that – you’ve guessed it - they will last 12 minutes.

The 2012 BBC Proms open on 13 July and end on 8 September. This is the full list of the 76 concerts. Book tickets here.

The Laugharne Weekend has become a fixture in the crowded calendar of festivals that now punctuates not just high days and holidays but the whole six months that make up British Summer Time. Carving a niche for itself as a halfway house between literature and music, Laugharne’s success is built on two key factors.

It began with a warning. Opening the fourth Tallinn Music Week, Estonia’s President Toomas Hendrik Ilves cautioned, “In a free society, it’s risk-free. In an un-free society, it’s not risk-free. It’s not all fun.” From behind a hotel conference room lectern, he then began rolling a video of Russia’s Pussy Riot being arrested in Moscow a few days earlier. Not everyone can make their point, make their music, choose how they want to get it across.
