If you can hire a professional photographer, you should. The results they get are amazing and will make your social media content look much better.
However, even amateur photographers like myself can take photos of value by capturing those moments that most fans are not privy to. For instance, here is a shot I took yesterday at the sound check for clients Cowboy Mouth. It is not as exciting as photos from the concert, but I think it is a cool, contemplative moment that most people don't get to see.
