A CAPITOL FOURTH, featuring musical performances by some of the country's best known and award-winning musicians in performance with the National Symphony Orchestra, is broadcast live in from the West Lawn of the United States Capitol before a concert audience of hundreds of thousands, millions more at home, on National Public Radio and around the world to our troops on the American Forces Radio and Television Network. Bringing viewers the most spectacular fireworks display anywhere in the nation, the 30th annual broadcast of A CAPITOL FOURTH captures the pyrotechnics from every vantage point with 18 TV cameras stationed around the city -- including the U. S. Capitol, the White House, the Washington Monument and across the Potomac River. In tribute to America's 234th birthday, the show is capped off with Tchaikovsky's "1812 Overture," complete with live cannon fire provided by the United States Army Presidential Salute Battery.
