Another dance SM weighing in.
When I first started calling dance shows, I wanted to be out front. Better view, less distractions and, since I was almost responsible for the lighting, I could actually see the lights.
After a year with the company, they asked me to move backstage, so I did. Now I wouldn't want to call a dance show from any other location.
Yes sometimes people approach me an inopportune times, but I am right there if they need me. Ideally, I have all my cues lights, monitors and page mics in place, but even if I don't have those things, I am much more connected with the performance and the flow of the event. I can call an entrance cue perfectly because I can actually see the dancer as they enter, not once they are already onstage.
My experiences calling dance from backstage has lead me to want to call theatre from backstage too. (I have done this a few times always to great success). Clearly backstage doesn't work for all theatre shows, but when it can work out, I feel the performers appreciate having me nearby.
