The "Chromatics" is a unique, high-energy, a-capella vocal band that delights audiences across the country. Originally formed in 1993 at NASA's Goddard Space Flight Center, the Chromies wrote and produced their astronomically correct songs, a project they call AstroCappella. "The Sun Song" is one of them. Also, one of their CD's has even flown in space! No kidding!
