hit single, "Rayando el Sol". The group toured heavily in support of the album, performing more than 250 times throughout Latin America, including shows in Mexico, Peru, Ecuador, and Colombia. 1990–96: Commercial success In 1991, they added two new members to the group Iván González on keyboards and César "Vampiro" López on guitar. Ulises Calleros no longer performed with the group, but became one of their managers. On 27 October 1992, the band released ¿Dónde Jugarán Los Niños?, 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, López and Iván González left the group due to musical and personal disputes.

The initial reaction to Cuando los Ángeles Lloran was mixed and the first single, the funk-influenced "Déjame 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. 1997–2007: Sueños Líquidos, Revolución de Amor, and Amar es Combatir In 1997, the group released Sueños Líquidos, an album about the highs and lows of love, with songs like "Clavado en un bar" and "En el Muelle de San Blás", recorded in Puerto Vallarta and released simultaneously in 36 countries. The recording received a Grammy Award for Best Latin Rock/Alternative Album. The group performed acoustically in Miami for Latin America's
