I've been working with bands and shooting live gigs since the early 1970's. In more recent years I've worked with the lighting enginner to ensure I get good lighting for photographs, and I've sometimes chosen the venue as well. It does help that I've worked alongside one musician now part of a record company for well over 30 years.
Since the late 70's I've nearly always used auto exposure, the lighting varies so wildly, but that's not always the case.
Use of film is a luxury these days, and the Kodak & Fuji push process E6 films I relied on are long gone. I used to shoot in the evening and process E6 and XP2 the next morning, but clients now expect digital copies the next morning !!!!
