Background: Chao's mother, Felisa Ortega, is from Bilbao, Basque Country, and his father, writer and journalist Ramon Chao, is from Vilalba, Galicia. They emigrated to Paris to avoid Francisco Franco's dictatorship--Manu's grandfather had been sentenced to death. Shortly after Manu's birth, the Chao family moved to the outskirts of Paris, and Manu spent most of his childhood in Boulogne-Billancourt and Sevres. As he grew up he was surrounded by many artists and intellectuals, most of whom were acquaintances of his father.
Context: Heavily influenced by the UK rock scene, particularly The Clash, The Jam and Dr. Feelgood, Chao and other musicians formed the Spanish/English rockabilly group Hot Pants in the mid-1980s. The group released a demo entitled "Mala Vida" in 1984, which received plenty of local critical praise but otherwise gained them little attention. By the time the group released their first album in 1986 the Parisian alternative music scene had taken flight, and Manu, his brother Antoine Chao, and friends such as Alain from Les Wampas formed Los Carayos to incorporate this sound with the rockabilly and punk styles of Hot Pants. Los Carayos remained a side project of the artists for eight years, releasing three albums in the first two years followed by a final album in 1994.  In 1987, the Chao brothers and their cousin Santiago Casariego founded the multiracial band Mano Negra. Manu Chao said in Alt.Latino in 2011, "Mano Negra started playing in a subway in Paris before the band started to be known and selling records. We started in a subway for a living. This is what made the musicians of Mano Negra. And so the people using the subway in Paris was very eclectic. There was people from a lot of different countries, different cultures. So we have to be able to play all kind of music to please all the people in a subway. So that was a perfect school to learn a lot of different styles of music." Starting on a smaller label, the group released a reworked version of the Hot Pants single "Mala Vida" in 1988, which quickly became a hit in France. The group soon moved to Virgin Records, and their first album Patchanka was released the following year. Though the group never gained much fame in the English-speaking market, popularity throughout the rest of the world soon followed, reaching the Top 5 in the Netherlands, Italy and Germany. The band achieved some fame in South America with 1992's Cargo Tour, where it played a series of shows in port cities, performing from a stage built into their tour ship's hold. Mano Negra also performed a tour through much of Colombia in a retired train, the "Ice Express". Still, rifts began to grow among band members during the port tour and the following year's train tour; many band members, including Manu's brother Antoine, had left the group by the end of 1994. Following that year's release of their final album, Casa Babylon, Manu Chao moved the band to Madrid, but legal problems with former band mates led Chao to disband the group in 1995.  Mano Negra's sound is mostly characterized by energetic, lively rhythms, symbolized by the title of their first album, Patchanka, derived from the word pachanga (which is a colloquial term for "party"), and a distinct informality which allows the audience to get involved and feel close to their sound. Mixed music genres are present throughout their albums. Manu Chao is friends with Gogol Bordello and that group has covered Mano Negra's song "Mala Vida" on their own and with Chao beginning in 2006.  In 2003 he approached Amadou & Mariam and later produced their 2004 album Dimanche a Bamako ("Sunday in Bamako"). His song "Me llaman Calle", written for the 2005 Spanish film Princesas, earned that film a Goya nomination for Best Original Song. It has been released in 2007's La Radiolina. Vocals from the song are included in the Go Lem System song "Calle Go Lem". Time magazine named "Me Llaman Calle" one of The 10 Best Songs of 2007, ranking it at No. 8. Writer Josh Tyrangiel observed,  Chao's warm singing over Jose Manuel Gamboa and Carlos Herrero's leaping Flamenco counter melody creates a direct emotional line to the core of this mid-tempo ballad. With its easy melody and universal rhythm Me Llaman Calle walks proudly in the shadow of Bob Marley, the last guy who made world music this disarmingly simple.  Manu Chao was featured on the album True Love by Toots and the Maytals, which won the Grammy Award in 2004 for Best Reggae Album, and showcased many notable musicians including Willie Nelson, Eric Clapton, Jeff Beck, Trey Anastasio, Gwen Stefani / No Doubt, Ben Harper, Bonnie Raitt, The Roots, Ryan Adams, Keith Richards, Toots Hibbert, Paul Douglas, Jackie Jackson, Ken Boothe, and The Skatalites.  His song "La Vida Tombola" was featured in the documentary film Maradona by Serbian filmmaker Emir Kusturica. The song "La Trampa", recorded with Tonino Carotone for the compilation album Fuerza! was used as the theme song for the short-lived improvisational comedy Drew Carey's Green Screen Show.  The songs "Bongo Bong" and "Je ne t'aime plus", which appear back-to-back on Clandestino, were covered by British singers Robbie Williams and Lily Allen, who recorded them as a single track, "Bongo Bong and Je Ne T'aime Plus" and released it as a single from the album Rudebox.  Chao believes that our world lacks spaces for "collective therapy" and describes his concerts as small temporary spaces where people of different backgrounds can come together  Chao's lyrics provoke his audience to think about immigration, love, living in ghettos, drugs, and often carry a left-wing message. This reflects Chao's own political leanings--he is very close to the Zapatistas and their public spokesman, Subcomandante Marcos. He has many followers among the European left, the Latin American left and the anti-globalisation and anti-free trade movements. Chao is a founding member of ATTAC. Punk and reggae historian Vivien Goldman commented of his work, "I was writing about Good Charlotte and The Police. They adopted the trappings of punk. They aren't bad groups, but the punk aspect is more manifested by somebody like Manu Chao. He's one of the punkiest artists out there I can think of. It's an inclusionary spirit that is punk."  Chao uses his Facebook and Twitter accounts to show support to many causes and current movements including Anti Globalization, Indigenous Peoples' Rights, Sex Workers' Rights, Women's Rights, Environmental Justice, and more. He also uses his personal website to provide news on events related to these causes and movements.  Since 1991, Chao has been working with La Colifata, which is an NGO made up of a group of patients and ex patients of Hospital Borda, a psychiatric hospital in Buenos Aires, Argentina. Chao uses both a website and a Facebook account to show the work he does with these patients and ex patients. On their Facebook page he explains that the mission of this group is to diminish the stigma that people place on mental illness and to promote the use of services that are meant to help those with mental illnesses.
