These images are taken from the archives of Nick & Simon Robinson, brothers who attended almost every significant rock gig in Sheffield (and elsewhere) during the 1970s. Every negative has been scanned at the highest possible resolution and painstakingly edited to maximise the detail. Some photos are not pin-sharp (you try keeping a camera still in the middle of an enthusiastic crowd!) but are presented since they perfectly capture the extraordinary musicians of the era, at their peak.
