Background: 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.
Context: 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.
Question: How well did this album do?

Problem: Background: Cristobal Perez was born on August 14, 1969 in San Antonio, Texas to Gilbert Perez, a computer programmer, and Carmen Medina. He is of Mexican-American ancestry. Perez's parents divorced in 1974, when he was four years old. His mother remarried in 1978.
Context: In spring 1995 Chris's father-in-law, Abraham found out Yolanda Saldivar, who managed Selena's boutiques and fan club, was embezzling money. They held a meeting in early March where it was rumored they had a sexual relationship, with Saldivar denying she had anything to do with fiscal discrepancies in checks that were found written in her name. Selena tried to repair her friendship with Saldivar despite her father's warnings. On March 30, 1995, Selena and Chris met with Saldivar at a motel to recover missing financial papers for tax purposes. When Selena arrived home she found that Saldivar did not give her the correct documents. She phoned Saldivar, who tried to convince Selena to return to her motel room alone. Chris insisted that it was too late, and he did not want Selena driving alone at night. Selena then agreed to meet with Saldivar the next morning.  On March 31, Selena woke up early to meet Saldivar at the motel where she was staying. She met with Saldivar, who delayed the transfer of papers with a story about having been raped in Mexico. Selena took Saldivar to a local hospital, where doctors found no evidence of rape. When they returned to the motel room, Selena ended their four-year working relationship. As she turned to leave, Saldivar reached into her handbag, pulled out a Taurus Model 85 .38 caliber revolver, pointed it at Selena and pulled the trigger. The bullet entered Selena's right shoulder blade from the back, piercing a major artery running from her heart and exiting from just below her right collarbone. She ran to the motel lobby and collapsed to the floor. As the motel employees gathered round, she named Saldivar as her assailant. Selena was transferred to a nearby hospital, where doctors found the damage irreparable. She was pronounced dead within the hour.  Chris couldn't eat for two days after his wife's murder. In his book he says that when he could not sleep he began abusing alcohol and other drugs, and went into seclusion. Family members noticed he was rapidly losing weight. Chris felt guilty for not protecting Selena from Saldivar.  In 1996, he moved out of his Corpus Christi house and back in with his father in San Antonio. John Garza introduced him to Venessa Villanueva, and after getting to know each other they became a couple in 1998. In 2001 Chris married Villanueva and they had two children, a boy and a girl.  Although it was rumored that Villanueva did not want to divorce, and wanted to try and work things out in their relationship, the couple finally decided their relationship was irreconcilable. They filed for divorce in 2008. Despite getting married again and having two children, Perez has since remained in touch with the Quintanillas following Selena's death.
