A jazz pioneer, Louis Armstrong was the first important soloist to emerge in jazz, and he became the most influential musician in the music's history. As a trumpet virtuoso, his playing charted a future for jazz in highly imaginative, emotionally charged improvisation. But Armstrong also became an enduring figure in popular music due to his distinctively phrased baritone singing and engaging personality, which were on display in a series of vocal recordings and film roles. His biggest hits include “What A Wonderful World,” “La Vie En Rose,” “Summertime,” “West End Blues,” “When You're Smilin',” “Blueberry Hill,” “Hello, Dolly!” and more.
