Do some searches also. There are some of us that do quite a bit of this and we have discussed it and made suggestions on several recent threads, some in the portrait forum too I think. There's one lower down about using older DSLRs etc. Search concrt photography, musicians, bands, coffee houses etc. Also look on some of the Nikon Wednesday threads, there have been a fair amount of great stage shots on there. OK, happy clicking.

Hi Megan,
I took a look at the first few pages of your flick gallery images. Jeff's article as suggested by Nadine is really a very useful one, except for one aspect, most of the British based small concert venues don't have balconys as such. I hope you take a note on lighting and framing. None of the pictures you have in the first few pages had particularly flattering lighting. The framing also seems to be an issue. Side shots are fine as long as there is something interesting in the posture or perhaps the musician looking your way.

Find a look that's all yours, and find a way to make it meaningful. Look for unusual moments, unusual arrangements of shape, color, and form. Look for the light. Repeat: look for the light. Distinguish yourself from every other snapshot artist in the room by developing an eye for composition, and don't forgive your own mistakes. The photographer is responsible for every single thing in the frame. If you do these things, your work will be sought after.
Technically: learn more about the basics of good exposure in difficult lighting situations. Learn to get the most out of RAW capture with your camera (esp. at high ISO settings). See if you can acquire some good fast lenses and a DSLR with good low-light capability.
