thanks

yes its not the easiest subject in the world to shoot, but lots of fun!
no, never use flash.
firstly, a lot of bands wont like it and also its only going to show up heads in front of you, bottoms of stages and not much else. use the lights on the stage and work with them.
i tend to not shoot when the lights are too red as it makes the performers faces look the same. if you can learn to work in time with the lighting guys, it will help hehe
himmm..use a high speed film..400
performers, especially guitarists and singers move around a lot so you have to wait for opportune moments. i wouldnt shoot them if they are running all over the stage on your first go. its a frustrating subject to shoot because youre dealing with lots of different elements at play, so dont be disconcerted if you come home with a roll of blurred photos.
if you can, id shoot digital, that way, you at least know what you need to fix and can change the speeds around.
i hope this helps in some way!
