Universally known as the King of the Mambo, Pérez Prado was the single most important musician involved in the hugely popular Latin dance craze. Whether he actually created the rhythm is somewhat disputed, but it's abundantly clear that Prado developed it into a bright, swinging style with massive appeal for dancers of all backgrounds and classes. Prado's mambo was filled with piercing high-register trumpets, undulating saxophone counterpoint, atmospheric organ (later on), and harmonic ideas borrowed from jazz. While his tight percussion arrangements allowed for little improvisation, they were dense and sharply focused, keeping the underlying syncopations easy for dancers to follow. Prado played the piano, but was often more in his element as the focal point of the audience's excitement; he leaped, kicked, danced, shouted, grunted, and exhorted his musicians with a dynamic stage presence that put many more sedate conductors and bandleaders to shame. With this blueprint, Prado brought mambo all the way into the pop mainstream, inspiring countless imitators and scoring two number one singles on the pop charts (albeit in a smoother vein than the fare that first made his name) as the fad snowballed. He was a star throughout most of the Western Hemisphere during the '50s, and even after his popularity waned in the United States, he remained a widely respected figure in many Latin countries, especially his adopted home of Mexico.
Elvis Aaron Presley[a] (January 8, 1935 – August 16, 1977), or simply Elvis, was an American singer and actor. Dubbed the "King of Rock and Roll", he is regarded as one of the most significant cultural figures of the 20th century. His energized interpretations of songs and sexually provocative performance style, combined with a singularly potent mix of influences across color lines during a transformative era in race relations, led him to both great success and initial controversy.
