Known as the “King of the Hillbilly Piano Players,” Moon Mullican (1909–1967) fused country, swing, blues, and early rock ’n’ roll into a sound all his own. A virtuosic pianist and expressive vocalist, he gained fame in the 1940s and ’50s with hits like “I’ll Sail My Ship Alone” and “Sweeter Than the Flowers.” Mullican’s rollicking piano style and rhythmic flair influenced later artists from Jerry Lee Lewis to Hank Williams, securing his legacy as a pioneering bridge between honky-tonk country and the birth of rockabilly.
