Back in September, I was fortunate enough to interview David Hurn, the Magnum photographer perhaps most renowned for capturing the essence of 1960s culture - not least behind the scenes of the Beatles film A Hard Day's Night.
In some ways, Denis O'Regan did much the same for the late 1970s. His images of some of the most recognisable faces in punk have become iconic, and proved to be the catalyst for an extraordinary career as a professional rock photographer. There can't be too many people who've got to know the real David Bowie, toured with the likes of Pink Floyd and The Rolling Stones, and partied with Prince and Bob Marley.
At the recent exhibition The Art Of Punk And New Wave, which also featured photos by his long-term colleague and friend Chalkie Davies, I had the pleasure of speaking to O'Regan about how he got started, the significance of punk and the status of rock photographers today.
