Come On!

This is a very good shot! Not only did you get Ashley in an interesting pose and came up with a witty title that has to do with the shot, but you also were able to figure out how to cut down on the pixelation of the photos. One thing you might want to keep in mind when you are taking shots. If your not shooting still life, sport is your best friend. This will cut down on the blur and the grain. One thing I have found while shooting at concerts is that the performers move very fast. In your settings on your camera there should be a sub menu to decide just how many photos you want to take in the span of a few seconds.
This setting is called a shutter speed. Most run of the mill cameras don't have a very fast shutter and this is why you don't see professional photographers running around with pocket Nikon cameras. Now, if you have a nice camera that isn't a pocket, and you are able to change the shutter speed, but don't have an SLR, you probably only have a few settings.
For instance, I have a Nikon Coolpix L820. This camera only has three shutter speeds. 1/1500-1 seconds, 1/4000 sec. (which is the maximum speed), and 4 seconds.
While shooting my first concert I used 1/1500 which is the default for my sport setting. Later I found that this speed wasn't fast enough most of the time. Using the 1/4000 second setting was much better, but the down side to that was that I only get about 30 pictures in a set while I'm using this setting and 30 pictures in less than 1 second doesn't give you a wide range of poses. If you haven't messed around with the settings in your camera yet, I would suggest you do so before your next concert.
Another thing that would take down the grain effect on your shots would be if you got closer to them. When you zoom while using sport the photos become very grainy, and the lights that they use don't help with the grain either. So getting close to the stage wouldn't hurt. It's an uphill battle I know, but if you have a friend there who can assist with the advance to the stage then that will help. When I was taking my shots I was right next to the mosh pit and thankfully there was a guy next to me that helped anchor me to my spot, otherwise I would have found myself with a broken camera, nose, arm, and God knows what else. Which might or might not been a good thing because I hear they are super sweat to the girls that get hurt at their shows, but I wouldn't have been able to take any pictures because, like I said before, my camera would be broken.
Now back to the actual photo. I think that this shot would have benefited from you cropping it so that only Ashley, and CC since he is right under his guitar neck, were in the shot. This would have kept the focus on Ashley, and enforcing the "come on!" title once more. Remember, when you take a shot you don't need to have the whole shot in it. Many of my photos are cropped so that the impact of the pose isn't taken away from. With concerts it's hard to get a full sized shot with focal point being the person you took the picture of.
All in all this was an awesome photo and I'm glad to say that you did an amazing job of bringing down the grain. If you do those things I mentioned you wont have to compromise detail for lack of grain. Keep up the awesome job!
