I need a faster lenses for low light concert photography.any suggestions? - 1

I'm in need of a faster lenses for taking photographs in low light. I'm not a fan of flash photography but I often shoot in low light. Lately I have been taking photos of local bands… Who come out blurry in my shots. I have a nikon D300. I'm also a college student, so I can't afford something too expensive.

I will happy to have any tips or suggestions.
Thanks

Added (1). I can be close or far away. I have a 55-200mm that I was using before but it wasn't fast enough. I was looking at the 35mm f/1.8. I also did have my iso cranked up

Get a fixed 35mm f/1.8 lens. HUGE aperture takes great pics in low light. Also consider raising the iso on the camera.

How close will you be? If you're going to be close, you can't beat a 50mm f/1.4 for value and sharpness.
