Had the pleasure of meeting Brian when he came over to Barcelona to 'shoot' the Movin' On Weekender and am looking forward to catching up with him again at Radcliffe this weekend. My advise is if you see him at your local event then have a chat with him. He's as nice a guy you're ever likely to meet and he's very open about what he's doing - more than happy to explain the technical side of his work and, as discussed above, never in anybody's face.
He's not just some bloke with a camera and nor is he trying to bring something new to the table - it's his profession and he's simply documenting the scene as it is today. Check out some of his other work - he was the artistic director for Oasis & Verve and has produced some of the most iconic album covers.
Andrew.
