This the singing group my wife is part of. They had a gig in Ft. Worth last night and this was shot there. It is a bit noisey (the photo girls, not your singing) but I left it that way intentionally.
From right to left the girls are Marla Touchstone, Leighann Heil, Rikie Floyd and Hilary Walton. You can see and hear Siren's Song at their website. http://www.sirenssong.net
