"Music is supposed to have meaning," says Dr. Adolphus Hailstork whose music captures the tribulations and the occasional triumphs of African Americans in this country. Hailstork's 80th birthday year got off to an impressive start with a performance of his music as part of the Presidential Inauguration ceremony of Joe Biden. Since then there has been a world premiere of a concert aria he composed to commemorate the centenary of the Tulsa Massacre and he awaits the premiere of his recently completed Fourth Symphony.
