I'll be photographing a 3 piece rockabilly band later this afternoon- male vocalist/guitarist, male vocalist/drummer (main vocals- I believe he stands up when he plays/sings, like the guy from the Stray Cats), and female upright bass player. They're wanting to use the shots for flyers and other publicity stuff. Will probably do a couple shots around some classic cars as well as some "action" shots of them playing and some headshots, but also want to do some on a backdrop (outdoors, natural afternoon light). Any suggestions on posing them, with and without instruments, or other ideas? Having never done this before, I don't want them to look stilted or awkward. Thank you!
