Louis "Satchmo" Armstrong is the single greatest influence in all of American popular music. He stands out not only as a master of the jazz trumpet, but as a superlative vocalist whose unique phrasing made every song he sang his own. According to the ever-elegant Duke Ellington, "Louis Armstrong was the epitome of jazz, and always will be. He is what I call an American standard; an American original". The Ambassador of Jazz features ten timeless classics, including "On the Sunny Side of the Street" and "Just a Gigolo".
