From December 9th, 2010 through January 23rd, 2011, UK art gallery Proud Camden will host Adrian Boot's London Calling: The Clash exhibit. The venue described the event:
This unique exhibition is a photographic portrait of the most influential punk rock band, credited with pioneering the advocacy of radical politics in rock, and includes never before seen images. Photographed rehearsing at their studio in the Gin House at the Stables Market in Camden which was also the site of the original Proud Galleries in Camden, this exhibition marks a true homecoming for Boot's extraordinary images of this cult band.
You can find a great summary of Adrian Boot's career and photographs at the Proud Camden website.
