So a friend of mine is in a David Bowie cover band. As a cancer fundraiser, they threw on a concert and asked me to shoot for them. Using my D7000 and a few wide angle lenses (35mm and 11-16mm) I managed a few good shots from a massively crowded venue.
No photo pit so I had to eel my way through the throngs of attendees and capture from there. The band was very true to the original, with the lead singer even looking like Bowie.
