It’s a dangerous world: the euro disintegrating, Britain nearly broke, ongoing wars. The Festival of Dangerous Ideas is a day for art and activism, for the new, the seditious, the ridiculous...

The old ideas are bust. The Festival of Dangerous Ideas is a day of activism and art, debates and DJs, workshops, comedy, interventions and inspiration.

Pandit G of Asian Dub Foundation joins Sam Duckworth (get cape. wear cape. fly), rap artist Reveal, comedian Josie Long and performance art perverts Sh!t Theatre flex their creative muscles against the hand-wringing of the coalition toffs in Whitehall.

Get involved through hands-on offerings including a ‘tweet-out', an interactive Theatre of the Oppressed workshop, a day-long guerilla film course, a Free shop, live graffiti walls and much more.

Guerrilla artists Peter Kennard and Rob Montgomery will launch a call to arms to artists everywhere. Proclaiming that ‘art belongs on the streets’, they promote using art as a tool of resistance – all this alongside an all-day live graffiti wall from notorious scribbler Stik.

Paul Mason (BBC) and Owen Jones (author of Chavs: The Demonization of the Working Class) join subversive authors and activists Nina Power and Sanum Ghafoor to discuss the radical ideas needed to confront the bleak landscape of austerity Britain.

Bringing the spirit of revolution to London are Egyptian MP Nasr-Eddin al-Zoghbi and Marwa Farouk of the Socialist Renewal Current and activists from Greece describing what it means to be at the frontline of Europe’s austerity project.

DJs and live music, dancing, debates and dangerous ideas are going on late with the Rich Mix bar open till 1am.

Tickets are £10/£5 concessions and are available online from http://www.richmix.org.uk/whats-on/event/the-festival-of-dangerous-ideas/

The event is organised jointly by Counterfire, ISG of Scotland, book publishers Verso and the Rich Mix.
