For 25 years, The Chromatics have been a high-energy vocal band on a mission to delight audiences with a full spectrum of songs about science, technology, life, and their intersections. They have taken their astronomically correct a cappella songs (a project called AstroCappella) from coast to coast, and their CD has flown in space (for realz!). Here on earth they’ve captivated young and old alike in many places, including the Kennedy Center’s Millennium Stage.
