If we're discussing concert photography, you've got some great crowd photos, one or two good performer photos and I think you'll throw the rest of them away when the next batch of photos comes around. The good photos have succeeded in capturing the raw energy of a punk/hardcore/metal concert in a small venue.
I see no point in going into the technical details, other than agreeing that the grain/grittiness adds to the final image.
ps: I have been doing concert photography for the past three years, I've calculated I've done something like 500 concerts during these three years... and I only do them in digital. I like film but I need the images as soon as possible and with the minimum hassle.
