Presenting intricate arrangements comes so naturally for the members of OneVoice that it's easy to forget the group's members are only high school students. 

Under the direction of Dr. J.D. Frizzell, the group from Briarcrest Christian School in Memphis, TN, has accomplished quite a bit in just a few years, including serving as the host of the National A Cappella Convention since 2015.

From appearances on "America's Got Talent" and collaborations with Grammy winners to numerous awards and nominations, this program has quickly become a leader in the scholastic community.

Demonstrating their poise and talent, OneVoice opened for Cluster at the 2018 NACC on Saturday. Here's a sample of what the group sounds like on "Sun", arranged by Rob Dietz.
