Ernie Haase & Signature Sound is a Southern Gospel vocal quartet founded in 2002 by Ernie Haase, former Cathedral Quartet tenor, and Garry Jones, former Gold City pianist. In 2012, it consists of Doug Anderson (baritone), Devin McGlamery (lead), Paul Harkey (bass) and Ernie Haase (tenor). While Ernie Haase and Doug Anderson have been with the group from the start, the lineup of the band has changed a few times. The band has released 17 albums and 8 DVDs, which feature many other Christian artists as well.
The Cathedral Quartet announced their farewell tour in 1999. Lead singer Glen Payne died on October 15, 1999 before the end of the tour. Upon request of Glen Payne, the remaining members finished the tour with pianist Roger Bennett performing Payne's vocals. Following the tour Bennett and baritone Scott Fowler formed Legacy Five while Ernie Haase continued his solo career.
