Millie danced to jazz in her Italian neighborhood. Pedro danced to Latin songs in his Puerto Rican neighborhood. It was the 1940s in New York City, and they were forbidden to dance together... until, first, a band and, then, a ballroom broke the rules. Machito and His Afro-Cubans hit the scene with a brand-new sound, blending jazz trumpets and saxophones with Latin maracas and congas creating Latin jazz: music for the head, the heart, and the hips. Then the Palladium Ballroom issued a bold challenge to segregation and threw open its doors to all. ¡Mambo Mucho Mambo! portrays the power of music and dance to transcend racial, religious, and ethnic boundaries.
