Problem: Background: Carlos Santana  audio  (born July 20, 1947) is a Mexican and American musician who first became famous in the late 1960s and early 1970s with his band, Santana, which pioneered a fusion of rock and Latin American jazz. The band's sound featured his melodic, blues-based guitar lines set against Latin and African rhythms featuring percussion instruments such as timbales and congas not generally heard in rock music. Santana continued to work in these forms over the following decades. He experienced a resurgence of popularity and critical acclaim in the late 1990s.
Context: More radio-friendly singles followed from Santana and the band. "Winning" in 1981 (from Zebop) and "Hold On" (a remake of Canadian artist Ian Thomas' song) in 1982 both reached the top twenty. After his break with Sri Chinmoy, Santana went into the studio to record another solo album with Keith Olson and legendary R&B producer Jerry Wexler. The 1983 album Havana Moon revisited Santana's early musical experiences in Tijuana with Bo Diddley's "Who Do You Love" and the title cut, Chuck Berry's "Havana Moon". The album's guests included Booker T. Jones, the Fabulous Thunderbirds, Willie Nelson and even Santana's father's mariachi orchestra. Santana again paid tribute to his early rock roots by doing the film score to La Bamba, which was based on the life of rock and roll legend Ritchie Valens and starred Lou Diamond Phillips.  The band Santana returned in 1985 with a new album, Beyond Appearances, and two years later with Freedom.  Growing weary of trying to appease record company executives with formulaic hit records, Santana took great pleasure in jamming and making guest appearances with notables such as the jazz fusion group Weather Report, jazz pianist McCoy Tyner, Blues legend John Lee Hooker, Frank Franklin, Living Colour guitarist Vernon Reid, and West African singer Salif Keita. He and Mickey Hart of the Grateful Dead later recorded and performed with Nigerian drummer Babatunde Olatunji, who conceived one of Santana's famous 1960s drum jams, "Jingo". In 1988 Santana organized a reunion with past members from the Santana band for a series of concert dates. CBS records released a 20-year retrospective of the band's accomplishments with Viva Santana! double CD compilation. That same year Santana formed an all-instrumental group featuring jazz legend Wayne Shorter on tenor and soprano saxophone. The group also included Patrice Rushen on keyboards, Alphonso Johnson on bass, Armando Peraza and Chepito Areas on percussion, and Leon "Ndugu" Chancler on drums. They toured briefly and received much acclaim from the music press, who compared the effort with the era of Caravanserai (1972). Santana released another solo record, Blues for Salvador (1987), which won a Grammy Award for Best Rock Instrumental Performance.  In 1990, Santana left Columbia Records after twenty-two years and signed with Polygram. The following year he made a guest appearance on Ottmar Liebert's album, Solo Para Ti (1991), on the songs "Reaching out 2 U" and on a cover of his own song, "Samba Pa Ti". In 1992 Santana hired jam band Phish as his opening act.
Question: were these appearances in concert?
Answer: In 1988 Santana organized a reunion with past members from the Santana band for a series of concert dates.

Problem: Background: Ramzan Akhmadovich Kadyrov (Russian: Ramzan Akhmatovich Kadyrov, IPA: [ra'mzan ax'mat@vjItc ka'dir@f], Chechen: K'adar Akh'mat-kIant Ramzan Qadar Axmat-khant Ramzan; born 5 October 1976) is the Head of the Chechen Republic and a former member of the Chechen independence movement. He is the son of former Chechen President Akhmad Kadyrov, who was assassinated in May 2004.
Context: After his father, then President, was assassinated on 9 May 2004, Ramzan was appointed as the First Deputy Prime Minister of the Chechen Republic on 10 May 2004.  When his sister was detained by the Dagestan police in January 2005, Ramzan and some 150 armed men drove to the Khasavyurt City Police (GOVD) building. According to the city mayor, Kadyrov's men surrounded the GOVD, forcing its duty officers against a wall, and assaulted them, after which they left the building with Zulay Kadyrova, "victoriously shooting in the air."  In August 2005, Ramzan declared that "Europe's largest mosque" would be built in place of the demolished ruins of Grozny's shattered downtown. He also claimed that Chechnya is the "most peaceful place in Russia" and in a few years it would also be "the wealthiest and the most peaceful" place in the world. He said that the war was already over with only 150 "bandits" remaining (as opposed to the official figures of 700 to 2,000 rebel fighters), and that thanks to his father, 7,000 separatists had already defected to the Russian side since 1999. When responding to a question on how he is going to "avenge the murder of his father", Ramzan said:  I've already killed him, whom I ought to kill. And those, who stay behind him, I will be killing them, to the very last of them, until I am myself killed or jailed. I will be killing [them] for as long as I live... Putin is gorgeous. He thinks more about Chechnya than about any other republic [of the Russian Federation]. When my father was murdered, he [Putin] came and went to the cemetery in person. Putin has stopped the war. Putin should be made president for life. Strong rule is needed. Democracy is all but an American fabrication... Russians never obey their laws. Everyone was stealing, and only Khodorkovsky is in jail.  He remained the First Deputy Prime Minister until November 2005.
Question: did that mosque get built
