Some context: Mana (Spanish: "manna") is a Mexican Rock band from Guadalajara, Jalisco. The group's current line-up consists of vocalist/guitarist Fher Olvera, drummer Alex Gonzalez, guitarist Sergio Vallin, and bassist Juan Calleros. Mana has earned four Grammy Awards, eight Latin Grammy Awards, five MTV Video Music Awards Latin America, six Premios Juventud awards, nineteen Billboard Latin Music Awards and fifteen Premios Lo Nuestro awards.
In 1991, they added two new members to the group, Ivan Gonzalez on keyboards and Cesar "Vampiro" Lopez on guitar. Ulises Calleros no longer performed with the group, but became one of their managers. On 27 October 1992, the band released ?Donde Jugaran Los Ninos?, an album that spawned several hits (including "Vivir Sin Aire," "Oye Mi Amor," and "De Pies a Cabeza"). The record sold over 3 million copies worldwide and became the best selling Spanish-language rock album of all time. The band undertook an international tour with 268 concerts in 17 countries.  In 1994, Lopez and Ivan Gonzalez left the group due to musical and personal disputes. Fher Olvera and Alex Gonzalez felt that their departure offered an opportunity to reinvent the group's sound, and searched throughout Mexico, Spain and Argentina to find a new guitarist. In the meantime, Mana released the live album Mana en Vivo before choosing Mexican guitarist Sergio Vallin to replace Lopez. In 1995, the band recorded a Spanish version of Led Zeppelin's "Fool in the Rain" for the tribute album Encomium.  On 25 April 1995, the group released Cuando los Angeles Lloran. The album was noted for its stylistic departure from the band's previous work, which saw the group experimenting with funk and soul music genres. Olvera explained shortly after the release of the album, "Basically, we're still the same Mana, but we're going through a funky, soulish stage. We want to have some fun and be a little louder." The initial reaction to Cuando los Angeles Lloran was mixed and the first single, the funk-influenced "Dejame Entrar", failed to reach the top ten on the Mexican Singles Chart. However, the album later caught on and sold 500,000 copies in the United States alone within five months of release.
