Born and raised in the Lone Star State of Dallas Texas, Mickey Raphael’s career as Willie Nelson’s Harmonica player has spanned almost three decades. His intelligent playing style has become a hallmark of Nelson’s crossover sound, earning him a large audience worldwide.

As a teenager, Raphael gravitated toward the Dallas folk music scene and fell under the spell of legendary harmonica great Don Brooks. “I went to this little coffee house one night and saw him playing and it just impressed me so much,” Raphael recalls. “He had moved to New York and was kind of a legend around Dallas. He sat me down one night after a show and showed me this little lick that went all the way up and down the harmonica, just a little pattern. Right away I just jumped about twenty steps from the little I already knew about the harp.”

Raphael eventually joined singer B.W. Stevenson’s band. One of his most enthusiastic boosters was University of Texas Football coach Darrell Royal, a passionate fan of country music.

One night in 1973, Royal invited Raphael to a post-game party in a Dallas hotel room and asked him to bring along his harps. The resulting informal jam session included Charley Pride and Willie Nelson, who passed around a guitar and took turns singing.
