Philip Dodd and Susan Hitch review a new production of Benjamin Britten's Gloriana at the ROH. As a new academic journal of Porn Studies is announced Philip and guests discuss whether being morally neutral about pornography is possible or desirable. Sarah Peverley is one of this year's New Generation Thinkers and in her first Night Waves outing she considers the figure of King Arthur. A major exhibition of Lowry's urban landscapes has opened at Tate Britain. Curator T.J.Clark talks about how Lowry's growing stature in the British art world coincided with the disappearance of the industrialised land he depicted.
