Willard "Ramblin'" Thomas, was an American country blues singer, guitarist, and songwriter best known for his expressive slide guitar playing. Born in the early 1900s in Logansport, Louisiana, he grew up in a musical family and learned guitar alongside his brothers, including fellow blues musician Jesse Thomas. After relocating to the Deep Ellum district of Dallas, Texas, Thomas developed a style influenced by Lonnie Johnson, Blind Lemon Jefferson, and Blind Blake. Between 1928 and 1932, he recorded for Paramount Records and Victor Records in Dallas and Chicago. His distinctive slide guitar technique is believed to have influenced musicians including Black Ace and Robert Johnson. He is known for songs like "So Lonesome," "Hard to Rule Woman Blues," "Ramblin' Man," and "Poor Boy Blues." Although his recording career was brief, Thomas left a lasting mark on the blues tradition. He reportedly died of tuberculosis in Memphis, Tennessee, in the mid-1940s.
