1, 4, 9 and 13. the shots are pretty dark so i am guessing you didn't have a lot of stage lighting to work with. though now checking EXIF, it looks like you weren't shooting yr zoom wide open, had ISO under 1600, and for the most part had fast enough shutter speeds. what metering mode were you using? there is a lot of contrast, so if you were using spot on faces, i can see why they'd be so dark.
