GUESTS: CLARK TERRY * Jazz musician and bandleader, plays trumpet and flugelhorn DAN MORGENSTERN *Director of the Institute for Jazz Studies, Rutgers University LAURENCE BERGREEN *Author,Louis Armstrong: An Extravagant Life (Broadway Books, 1997) Louis Armstrong has been called the greatest musician of the century. While some may disagree, one thing is certain: after Louis, no one played or sang popular music the same way. Miles Davis once said that you can't play anything on the trumpet that Louis hadn't played— even modern music. And while Armstrong may not have been gifted with a classically beautiful singing voice, the way he made a melody his own has inspired popular singers ever since; Frank Sinatra said that Louis Armstrong turned popular song into art. July 4th is the day when Armstrong's birthday is traditionally celebrated, so across the country this Independence Day, Americans will also be celebrating a hundred years of Pops. Join Juan Williams and guests for a look at the life and influence of Louis Armstrong, on the next Talk of the Nation, from NPR News.
