Started by then, bandleader and accordion player, Emilio Estefan, Jr., as the Miami Latin Boys, in 1975, as a weekend job.
The group name changed a year later to Miami Sound Machine, when Emilio invited a female singer, Gloria Fajardo and her cousin Merci Navarro, to join the band after a well performed audition on stage. In 1977, the group recorded their first album for a local label, Audiofon Records. Emilio would marry Gloria, a year later.
In 1980, CBS signed them to their new Latin American label, Discos CBS International and 1984's "Dr. Beat" disco smash, would lead the way to a deal with major CBS label, Epic.
The band, through it's course has undergone many musician changes and in 1989, would go uncredited, when Gloria Estefan recorded as a solo artist.
