Devin McGlamery sang lead for the Dixie Melody Boys from 2000-2004. He joined Karen Peck And New River in 2005 and remained with that group until 2009 when he returned to a male quartet format with Ernie Haase And Signature Sound. He filled the lead position until the departure of Doug Anderson in 2015 when he shifted to baritone, where he remained until his departure in 2021. Doug Anderson's return to the group coincided with this change.
McGlamery also released a solo project in 2013 on the Haase-owned StowTown Records label.
