COBB COUNTY, Ga. - Sonic Edge, the 17-member a cappella group from Pebblebrook High School’s Cobb County Center for Excellence in the Performing Arts (CCCEPA), has once again claimed the top prize at the International Championship of High School A Cappella (ICHSA).
What we know:
The group, made up of students from multiple arts disciplines, won the 2025 title after dominating each stage of the competition. They earned the highest scores in both the quarterfinal and semifinal rounds, with standout performances recognized for Best Soloist (Elise Lloyd), Best Vocal Percussionist (Amber Lowe), and Best Choreography.
On April 24, Sonic Edge delivered a show-stopping set at the ICHSA Finals in New York City, defending their national title and securing another Best Vocal Percussionist award for Lowe. The following night, they were invited to perform at the collegiate a cappella championship (ICCA).
"This win is not just about a trophy—it’s a testament to their hard work, resilience and the world-class training they’ve received," said CCCEPA Director Robert Connor.
Director of Vocal Music Trey Giddens added, "Their dedication to this group and their craft is unmatched, and I am so proud of them."
With their second consecutive national title, Sonic Edge has solidified its place as one of the top high school a cappella groups in the country.
