Tribute Quartet was formed by lead singer Gary Casto and baritone/pianist Josh Singletary. Both toured together with The Wilburns until that group came off the road. Bass singer Dennis Dugger is also a founding member of the group, coming to the group after singing in regional groups in Arkansas for years. The group's newest member, tenor Riley Harrison Clark, joined the group in 2010. He was eighteen at the time.
In the few short years they have been on the road, they have already accumulated several honors, including several radio hits and awards. Award highlights include a Singing News Fan Award for Horizon Group of the Year in 2008 and a SoGospelNews Breakthrough Artist of the Year award that same year.
