The band formed in 1986. They have said that they chose their name after suffering from several fevers due to trying to develop a name for themselves.. The original band members were Ricardo Garza jr., Pedro Ananis Espinoza, Rudy Rocha, Joe Angel Reynosa, Luis Ayala, Juan Manuel "Johnny" Tristan, and Eric Jimenez. In 1987 the group recorded their first album, Contagious, under their own label. This album gave them their first two charted songs, Vestida De Color De Rosa and Por Tu Culpa. Their 1991 album, On The Rise, produced the single Borracho De Besos, and sold over 100,000 copies in the United States, staying on the Billboard magazine chart for several weeks. In 1996 the group began to part ways. Eric Jimenez was the first to leave the group in order to write and produce for other artists. In February 1997 La Fiebre left EMI Latin records and signed on with Freddie Records. Shortly after the release of their album, Fenomenal, Luis Ayala left the group for personal reasons. In 1998 La Fiebre received a Grammy nomination in the category of Best Tejano Album for their album Fiebre Live En Concierto. The album was recorded at the Freddy Fest that took place in Corpus Christi, Texas and at a concert held in San Antonio, Texas.
