Ken Wilson's classic climbing book, Hard Rock, came out in 1974 and it now approaches the publication of its fourth edition. In this new edition, editor Ian Parnell has ensured Hard Rock continues to honour Ken's original concept, in particular keeping the route, not the climber, centre stage.

In this film, on Barton tells us here why this title is still as relevant as it was when first published and takes to the gritstone of Stanage Edge to tackle one of the original Hard Rock routes; The Right Unconquerable. Featuring an extract from Paul Diffley's interview with Ken Wilson originally featured in the poignant tribute 'Hard Rock - A Tribute to Ken Wilson'.
