Answer the question at the end by quoting:

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.
Generally, indigenous Mexicans live more poorly than non-indigenous Mexicans however, social development varies between states, different indigenous ethnicities and between rural and urban areas. In all states indigenous people have higher infant mortality, in some states almost double of the non-indigenous populations.  Some indigenous groups, particularly the Yucatec Maya in the Yucatan peninsula and some of the Nahua and Otomi peoples in central states have maintained higher levels of development while indigenous peoples in states such as the Guerrero or Michoacan are ranked drastically lower than the average Mexican citizen in these fields. Despite certain indigenous groups such as the Maya or Nahua retaining high levels of development, the general indigenous population lives at a lower level of development than the general population.  Literacy rates are much lower for the indigenous, particularly in the southwestern states of Guerrero and Oaxaca due lack of access to education and a lack of the educational literature available in indigenous languages. Literacy rates are also much lower, with 27% of indigenous children between 6 and 14 being illiterate compared to a national average of 12%. The Mexican government is obligated to provide education in indigenous languages, but many times fails to provide schooling in languages other than Spanish. As a result, many indigenous groups have resorted to creating their own small community educational institutions.  The indigenous population participate in the workforce longer than the national average, starting earlier and continuing longer. A major reason for this is that significant number of the indigenous practice economically under productive agriculture and receive no regular salaries. Indigenous people also have less access to health care.

How come?

lack of access to education and a lack of the educational literature available in indigenous languages.

Some context: Renaissance are an English progressive rock band, best known for their 1978 UK top 10 hit "Northern Lights" and progressive rock classics like "Carpet of the Sun", "Mother Russia", and "Ashes Are Burning". They developed a unique sound, combining a female lead vocal with a fusion of classical, folk, rock, and jazz influences. Characteristic elements of the Renaissance sound are Annie Haslam's wide vocal range, prominent piano accompaniment, orchestral arrangements, vocal harmonies, acoustic guitar, bass guitar, synthesiser, and versatile drum work. The band created a significant following in the northeast United States in the 70s, and that region remains their strongest fan base.
As The Yardbirds were transforming into The New Yardbirds (with Jimmy Page) in 1968 and then Led Zeppelin, departing members Keith Relf and Jim McCarty formed an acoustic duo called Together.  They released "Henry's Coming Home" b/w "Love Mum And Dad" as a single on Columbia Records in November 1968 without chart success.  In January 1969, Relf and McCarty organised a new group devoted to experimentation with rock, folk, and classical forms. In his book Mountains come out of the sky: an illustrated history of prog rock, Will Romano quoted McCarty:  This quintet -- Relf on guitar and vocals, McCarty on drums and vocals, plus bassist Louis Cennamo, pianist John Hawken, and Relf's sister Jane as an additional vocalist -- released a pair of albums on Elektra (US) and Island (UK-ILPS 9112), the first one, titled simply Renaissance, being produced by fellow ex-Yardbird Paul Samwell-Smith.  The band had begun performing in May 1969, before recording had commenced for the debut LP, mostly in the UK, but with occasional forays abroad, including festivals in Belgium (Amougies, October 1969) and France (Operation 666 at the Olympia in January 1970, and Le Bourget in March 1970, both in Paris). In February 1970 they embarked on a North American tour, but that month-long trek proved only marginally successful. Because of their Yardbirds credentials, they found themselves paired with bands such as The Kinks and their new classically oriented direction did not always go down well because audiences were expecting rock/blues-based material.  Beginning in the late spring of 1970 as touring began to grind on them, the original band gradually dissolved. Relf and McCarty decided to quit performing, and Cennamo joined Colosseum. Hawken organised a new line-up to fulfill contractual obligations to Island Records and complete the band's second album, Illusion which had been left unfinished.
was there a reunion?

IN: Departures (Japanese: okuribito, Hepburn: Okuribito, "one who sends off") is a 2008 Japanese drama film directed by Yojiro Takita and starring Masahiro Motoki, Ryoko Hirosue, and Tsutomu Yamazaki. Loosely based on Coffinman, a memoir by Shinmon Aoki, the film follows a young man who returns to his hometown after a failed career as a cellist and stumbles across work as a nokanshi--a traditional Japanese ritual mortician. He is subjected to prejudice from those around him, including from his wife, because of strong social taboos against people who deal with death. Eventually he earns their respect and learns the importance of interpersonal connections through the beauty and dignity of his work.

Japanese funerals are highly ritualized affairs which are generally--though not always--conducted in accordance with Buddhist rites. In preparation for the funeral, the body is washed and the orifices are blocked with cotton or gauze. The encoffining ritual (called nokan), as depicted in Departures, is rarely performed, and even then only in rural areas. This ceremony is not standardized, but generally involves professional morticians (Na Guan Shi , nokanshi) ritually preparing the body, dressing the dead in white, and sometimes applying make-up. The body is then put on dry ice in a casket, along with personal possessions and items necessary for the trip to the afterlife.  Despite the importance of death rituals, in traditional Japanese culture the subject is considered unclean as everything related to death is thought to be a source of kegare (defilement). After coming into contact with the dead, individuals must cleanse themselves through purifying rituals. People who work closely with the dead, such as morticians, are thus considered unclean, and during the feudal era those whose work was related to death became burakumin (untouchables), forced to live in their own hamlets and discriminated against by wider society. Despite a cultural shift since the Meiji Restoration of 1868, the stigma of death still has considerable force within Japanese society, and discrimination against the untouchables has continued.  Until 1972, most deaths were dealt with by families, funeral homes, or nokanshi. As of 2014, about 80% of deaths occur in hospitals, and preparation of the bodies is frequently done by hospital staff; in such cases, the family often does not see the body until the funeral. A 1998 survey found that 29.5% of the Japanese population believed in an afterlife, and a further 40% wanted to believe; belief was highest among the young. Belief in the existence of a soul (54%) and a connection between the worlds of the living and the dead (64.9%) was likewise common.
