Key Changes: Supreme Chord Turns 18

Key Changes: Supreme Chord Turns 18 is a celebratory a cappella concert marking the 18th anniversary of the vocal group Supreme Chord. The performance explores the theme of life transitions and milestones through a diverse repertoire spanning from Journey and Olivia Rodrigo to Jason Derulo and Peter Gabriel. The evening also features two guest ensembles from the D.C. area: Chord of Appeals, an all-gender community chorus founded in 2016 that has performed everywhere from local museums to the White House, and The Augmented Eight, a men’s group originally formed in 1950 by Ivy League and Stanford alumni that has entertained Washington audiences for over 75 years with a blend of old standards, modern pop, jazz, and show tunes.
