In America, Conover helped break down racial barriers related to jazz, participating in the famous Newport Jazz Festivals as well as serving on the National Endowment for the Arts to gain funding for jazz events. As a personal friend of Duke Ellington and many other jazz greats, Conover promoted their music over radio stations and at White House jazz concerts. His tenure at Voice of America lasted from 1955 until his death in 1996. Unfortunately, because of Congressional restrictions, his programs were not heard in the United States.
