The Rays were an American group formed in New York in 1955, and active into the early 1960s. They first recorded for Chess Records. Their biggest hit single was "Silhouettes," a moderately-slow doo-wop piece of pop music that reached number 3 on the Billboard Hot 100 in 1957 on Cameo after being initially released on the small XYZ Records. It sold over one million copies, and was awarded a gold disc. The song was written by Bob Crewe and Frank Slay, Jr. Also on XYZ, they had a minor hit with "Mediterranean Moon" a mid-chart hit with "Magic Moon" (by this time, XYZ was being nationally distributed by London Records).
