The group consisted of nine girls, at the time, ranging in ages 8 to 13; Jacqueline Laviolette, Carly Grayson, Jessica "Jess" Bonner, Crystal Evans, Kate Barker, Zoë Virant, Jessica Tarr, Gina Miele and Alexandra "Alex" Bilbo.
The group was established in the summer of 2005 by the group's vocal coach/executive producer Samantha Hammel, Scott Billington (a Grammy award-winning producer) and the CEO of Rounder Records, John Virant, the father of Zoe, one of the members of Girl Authority.
The girls have also shared the stage with the Jonas Brothers and Jesse McCartney, and have appeared on CBS' The Early Show.
Featured on this album is a version of the early previously unreleased Depeche Mode song called "Let's Get Together" that Vince Clarke re-wrote for the band.
Girl Authority recorded "The Star-Spangled Banner" in June 2006 and also a theme song for the Club Libby Lu store chain.
They also made a guest appearance in the book series Beacon Street Girls in July.
