Here's a pic I took of a singer friend of mine.
I used a 3 light set up, a beauty dish with an AB800 to create the rim light, another AB800 with a reflector to create the highlight on the left side of him, and a 580ex with a dome diffuser to fill the shadows on his back neck and face.
There's a more detailed write up about it, and a picture of the set up on my blog, if it peaks your interest.

Thanks for taking a look.
