Entertainers (mostly musicians) performing on stage. While there are a few shots where they're not actually ON the stage, They are still performing for the crowd. I guess that puts them on a metaphorical stage, if not a physical one.
This type of photography is a bit like sports or wildlife photography in that as you do it more and more, you start to learn to recognize patterns and anticipate where things are going to happen. There are quite a few shots in here (such as the image to the left) where there were many other photographers around but no others put themselves in a position to get the shot.

Things going on off stage. These are people not performing. This includes performers before or after their show as well as people in the crowd reacting to events.
While crowd shots may not seem difficult, trust me, it's VERY difficult to pay attentions to the crowd when ZZ Top is performing five feet in front of you.
I LOVE to get the special access shots that show being human, preparing for a show, or recovering after leaving it all on the stage.

Yeah, yeah. This is what a lot of you were looking for. Some of these were part of a project, some were test shoots to try out a technique or idea, some were just portfolio shoots. I'm always looking for something new, or a new twist on something old. I like to take a cliche shot and make it unique. I LOVE dramatic lighting and rarely use only natural light.

This is the catch-all. Shots I think are Interesting. People, places, things, moments...

Families, Weddings, Babies, and stuff like that

Bands, groups, troops and individuals artists. Your promo pic is often the first thing a busy talent buyer knows about you. This is where they first start to form an opinion of you. If you want to be viewed as a professional, don't go to an amateur for your promo shoot.
