Avalon

With an emphasis on tight harmonies, this vocal quartet was formed by a label exec at Sparrow Records, who put Michael Passons and Janna Potter (Long) together with Jody McBrayer and Nikki Hassman (Anders). (Two early members departed before the group ever got off the ground.) Standouts like the album A Maze of Grace and single "Testify to Love" prove the band's vocal chops. A revolving door of members had left only one original member, Janna Long, remaining by 2009. That same year, Long and her husband, Greg, teamed with husband and wife Jeremi and Amy Richardson for the aptly titled release Reborn.
