Attended Bhangra Blowout #17 with a Canon 5D and a 135mm f/2. In retrospect, I should have carried the 85mm f/1.8 and 50mm f/1.2 as well. The Canon 70-200mm f/2.8 would have been too slow. Was seated right up front, the second row—but to one side of the stage. The stage was at shoulder height. The floor lights often shone directly into the camera. The left edge of the view was cut off by a large loudspeaker, which intrudes into some of the shots below. Sometimes I could stand on a seat in the corner, gaining elevation but losing a frontal view.
Bhangra Blowout was loud, energetic, colorful, and everyone had great fun!
There was a young lady photographer there with a pair of cameras, one of which had a 85mm f/1.8; and she had considerably more mobility.
If perchance she visits this page, and leaves a URL to her photographs in the comments, that would be a great bonus.
