I recently had the band Ghyti visit my studio for some updated photos with their new guitarist Nick. The vignetted group composition (top left) was made by placing a toilet roll insulated with foil over the flash so it sent a very direct but randomly shaped beam of light at the faces. There's some light painting and double exposure in there too as well as a standard outdoor group shot at dusk.
You can check out and a music video from Ghyti below. The video was made using a series of stills I took with a Nikon d40. Find out more about Ghyti here https://www.facebook.com/ghytiandthephilanthropicorchestra
If you are a band and are interested in photography or video to help promote your work I take on a few projects a year so I might be able to help you out. Email me here : firstname.lastname@example.org
