Armando Antonio de Sequeira Romeu (September 13, 1937 – January 29, 2023) was a distinguished Cuban-American musician known for his versatility as a multi-instrumentalist, composer, arranger, and bandleader. Born into the renowned Romeu musical family in Havana, Cuba, he was trained by his mother, pianist-composer Zenaida Romeu González, and his grandfather, Armando Romeu Marrero, the long-time director of the Cuban Navy Band. His great-uncle, Antonio María Romeu, was a celebrated danzón composer and charanga bandleader, and his uncle, Rubén Romeu, was an influential mentor.

Armando Romeu's career began in the 1950s when he performed as a drummer with the orchestra at Havana’s Sans Souci cabaret. He later joined the Tropicana Club orchestra, playing drums in the house band and collaborating with international artists such as Nat King Cole. Romeu led several groups, including Los Fantásticos, Los Átomos, and Los Cinco de Armandito Sequeira, and worked with prominent artists such as Maggie Carlés and members of the Orquesta Cubana de Música Moderna and Orquesta Aragón.

His notable compositions include "Un Final Inesperado," which marked the beginning of Maggie Carlés's career, and "La vida siempre empieza," which became a theme for Cuban radio serials. Romeu's work with the Orquesta Cubana de Música Moderna contributed significantly to the evolution of Cuban music, paving the way for the formation of Irakere, a band he co-founded in 1973 alongside Chucho Valdés. Irakere became a groundbreaking ensemble, blending Afro-Cuban jazz with various musical genres and earning a Grammy Award in 1979.

Armando Romeu passed away in Miami, Florida, leaving behind a legacy that continues to influence Cuban and Latin music.
