The Harmonic Convergence Concert represents the culminating performance of the 2018 COA Nationals for Top Choirs. After an opening prelude from the Dougherty Valley High School Band, the concert features choral ensembles from across the country performing a mix of massed choir and individual choir repertoire. The evening concludes with an all-choir, world-premiere finale of a COA commissioned choral piece from Rosephanye Powell.
