Problem: Background: Indigenous peoples of Mexico (Spanish: pueblos indigenas de Mexico), Native Mexicans (Spanish: nativos mexicanos), or Mexican Native Americans (Spanish: nativo america mexicanos), are those who are part of communities that trace their roots back to populations and communities that existed in what is now Mexico prior to the arrival of Europeans. According to the National Commission for the Development of Indigenous Peoples (Comision Nacional para el Desarrollo de los Pueblos Indigenas, or CDI in Spanish) and the INEGI (official census institute), in 2015, 25,694,928 people in Mexico self-identify as being indigenous of many different ethnic groups, which constitute 21.5% of Mexico's population.
Context: The Law of Linguistic Rights of the Indigenous Languages recognizes 62 indigenous languages as "national languages" which have the same validity as Spanish in all territories where they are spoken. According to the National Institute of Statistics, Geography and Data Processing (INEGI), approximately 6.7% of the population speaks an indigenous language. That is, less than half of those identified as indigenous. 6,695,228 people 5 years or older were tallied as indigenous-language speakers in the 2010 census, an increase of about 650,000 from the 2000 census. In 2000, 6,044,547 people 5 years or older spoke an indigenous language.  In previous censuses, information on the indigenous speaking population five years of age and older was obtained from the Mexican people. However, in the 2010 census, this approach was changed and the Government also began to collect data on people 3 years and older because from the age of 3, children are able to communicate verbally. With this new approach, it was determined that there were 6,913,362 people 3 years of age or more who spoke an indigenous language (218,000 children 3 and 4 four years of age fell into this category), accounting for 6.6% of the total population. The population of children aged 0 to 2 years in homes where the head of household or a spouse spoke an indigenous language was 678 954. The indigenous language speaking population has been increasing in absolute numbers for decades, but have nonetheless been falling in proportion to the national population.  The recognition of indigenous languages and the protection of indigenous cultures is granted not only to the ethnic groups indigenous to modern-day Mexican territory, but also to other North American indigenous groups that migrated to Mexico from the United States in the nineteenth century and those who immigrated from Guatemala in the 1980s.
Question: What is the most popular (or a few of the most spoken) language(s) from these 62 ?
Answer: which have the same validity as Spanish in all territories where they are spoken.

Problem: Background: Mogwai () are a Scottish post-rock band, formed in 1995 in Glasgow. The band consists of Stuart Braithwaite (guitar, vocals), Barry Burns (guitar, piano, synthesizer, vocals), Dominic Aitchison (bass guitar), and Martin Bulloch (drums). The band typically compose lengthy guitar-based instrumental pieces that feature dynamic contrast, melodic bass guitar lines, and heavy use of distortion and effects. The band were for several years signed to Glasgow label Chemikal Underground, and have been distributed by different labels such as Matador in the US and Play It
Context: In 2006, the band provided the soundtrack to the film Zidane: A 21st Century Portrait, with the soundtrack album released the following year. The band's song "Auto Rock" was used in Michael Mann's 2006 film Miami Vice. The band also collaborated with Clint Mansell and Kronos Quartet on the soundtrack to The Fountain in 2006. Mogwai are also featured in the 2009 post-rock documentary Introspective. The band donated an exclusive track to the PEACE project in April 2010 in support of Amnesty International. In 2012, the band provided the soundtrack for the Canal+ French TV series Les Revenants (broadcast as The Returned in the UK). The album, Les Revenants, was released on 25 February 2013. The track "Kids Will Be Skeletons" was featured as part of the soundtrack of the story based video game Life Is Strange.  In 2015 the band supplied the music for Mark Cousins' documentary Atomic, Living in Dread and Promise. The soundtrack was reworked and released as Atomic on 1 April 2016, through Rock Action Records. The band carried out an extensive live tour of Europe and Japan performing the soundtrack against a backdrop of the screening of the film, beginning in Austria on 1 May 2016. They then announced a North American tour of the album for January 2017. The band also co-wrote the score to Fisher Stevens' 2016 documentary film about climate change Before the Flood. The score was performed and written by Mogwai, Trent Reznor, Atticus Ross, and Gustavo Santaolalla.  In 2016 Stuart Braithwaite took part in a documentary about Glasgow music, and Chemikal Underground Records, called Lost in France. The film was directed by Niall McCann and brought Braithwaite (along with members of The Delgados, Franz Ferdinand and others) to Mauron, Brittany, to recreate a gig they played just after Mogwai had formed. The film features Mogwai live, as well as footage of Braithwaite playing Mogwai tracks solo and interviews with Braithwaite and his old label-mates such as Alex Kapranos (Franz Ferdinand), Emma Pollock (The Delgados) and Stewart Henderson (The Delgados). It premiered at the Edinburgh International Film Festival to positive reviews and was called "Funny, vital and sobering" by Scotland's arts magazine The Skinny.
Question: did they do any other tours?
Answer: They then announced a North American tour of the album for January 2017.

Problem: Background: Earth Crisis is an American metalcore band from Syracuse, New York, active from 1989 until 2001, reuniting in 2007. Since 1993 the band's longest serving members are vocalist Karl Buechner, guitarist Scott Crouse, bassist Ian Edwards and drummer Dennis Merrick. Their third guitarist Erick Edwards joined the band in 1998. The band has released eight studio albums, three compilations, two live albums and six music videos.
Context: Earth Crisis had a huge impact on both the hardcore punk music and its ideals. MetalSucks said: "For anybody who was not in the hardcore scene back then, it is hard to describe the impact they had or how controversial they were. You either loved them or hated them for bringing both metal and veganism into the hardcore scene". Sociologist Ross Haenfler stated in The Vinyl Factory that "Earth Crisis became the face of straight edge throughout the 1990s" through "the convergence of 'radical' animal rights activism, a more aggressive 'metalcore' sound, and hardcore crews", becoming "one of the most controversial bands in the scene's history."  Their albums Firestorm, Destroy the Machines and Gomorrah's Season Ends were particularly influential for the emerging metalcore genre. According to Andrew O'Neill, "Earth Crisis inspired a much more heavy metal sound in hardcore" and "the distinction between the two [genres] started to crumble" shortly after those records were released.  To a large extent, Earth Crisis was responsible for the rising of vegan straight edge militancy in the mid- to late 90s, when veganism was rarely present in mainstream culture. Haenfler said that, while "earlier straight edge bands advocated vegetarianism - for example Youth of Today, Insted and Manliftingbanner", Earth Crisis "made animal rights (and environmentalism) central to the scene" as a "self-described 'vegan straight edge' band", "inspiring thousands of kids to give up animal products entirely." They also spawned many activists in the scene because their message "imparted the sense of urgency in a way that nothing else that ever come before had", according to Peter Daniel Young.  Some of their songs went on to be considered by some as anthems, such as "Firestorm" for straight edge and "Ultramilitance" for eco-terrorists. They also drew major media attention, having been featured and interviewed by CNN, CBS and The New York Times, while lead singer Karl Buechner was invited to address the Congress about teens and substance abuse.
