Overton Park Shell Slim Whitman Rubber Legs Elvis
The trio played publicly for the first time at the Bon Air club on July 17, 1954—Presley still sporting his child-size guitar. At the end of the month, they appeared at the Overton Park Shell, with Slim Whitman headlining. Here Elvis pioneered 'Rubber Legs', his signature style dance movement that he is best known for. A combination of his strong response to rhythm and nervousness at playing before a large crowd led Presley to shake his legs as he performed: his wide-cut pants emphasized his movements, causing young women in the audience to start screaming. Moore recalled, "During the instrumental parts, he would back off from the mike and be playing and shaking, and the crowd would just go wild". Black, a natural showman, whooped and rode his bass, hitting double licks that Presley would later remember as "really a wild sound, like a jungle drum or something".
