Problem: Background: Timbiriche (also known for a brief time as La Banda Timbiriche) was a Mexican pop music group. The group started as a children's group in 1982 and managed to evolve successfully into adulthood. Timbiriche is considered one of the most iconic Latin Pop acts of the 1980s and the early 1990s. It was the seed of numerous figures in the Latin American entertainment world, including successful singers like Thalia, Paulina Rubio and Edith Marquez, as well as actors, composers and conductors.
Context: After a few months of preparation, Timbiriche made its official debut on April 30, 1982 on the Mexican television show Siempre en Domingo, featuring Spanish singer Miguel Bose as its godfather. The group launches their first record production titled Timbiriche, which included the hit singles Amor para ti, Hoy tengo que decirte Papa, Y la fiesta comenzo and Somos amigos.  Due to the success obtained, and in order to have a wider repertoire in their presentations, the group recorded a second album titled La Banda Timbiriche, which included the hit singles La Banda Timbiriche, La vida es mejor cantando, Mexico and Mama . The group is also chosen to interpret the musical theme of the children's telenovela Chispita. In that same year, the group participates in a special of television where it shares scene with the group Parchis.  In 1983, the group released the album La Banda Timbiriche: En Concierto an album that was released under the concept of being a live album, although in fact the sound effects of the public were added in the recording studio. The album includes covers of songs in English and of musicals famous at that time like Time Warp of The Rocky Horror Picture Show, One Step (cover of Liza Minnelli and Goldie Hawn' song), Summer Nights (from the musical Grease) and Mickey (cover by Toni Basil). In this third album, the group already enjoyed a great acceptance in Mexico, receiving several disks of gold by the high sales of its albums.  At that moment of the group, the voices of the only two male members of the group were confused with those of the female members due to their young age. Because of this, the producers considered the idea of integrating a third male member into the group. The chosen one was Erik Rubin, who joins the band in December 1983. The band launches its fourth disc, titled Timbiriche Disco Ruido. The album was the first big challenge of the band, because it was not known what the public reaction would be to the new member, who had to go through many conflicts to adapt with his peers. However, the album had a good reception and contained hits such as Disco ruido and Adios a la escuela.
