Compiled by Smithsonian Folkways, "Jazz: The Smithsonian Anthology" is being called the most definitive box set on jazz to date. The compilation features 111 songs on six CDs that chronicle the history of jazz music through its legendary innovators: Armstrong, Ellington, Basie, Parker, Gillespie and many more. As producer and project director, Richard Burgess explains why the collection took seven years to complete.
