Background: The Funk Brothers were a group of Detroit-based session musicians who performed the backing to most Motown recordings from 1959 until the company moved to Los Angeles in 1972. They are considered one of the most successful groups of studio musicians in music history. The Funk Brothers played on Motown hits such as "My Girl", "I Heard It Through the Grapevine",
Context: In February 2004, surviving members of the Funk Brothers were presented the Grammy Legend Award at the 46th Annual Grammy Awards at the Staples Center in L.A. In March 2006, some remaining Funk Brothers were invited to perform on Philadelphia writer-producer-singer Phil Hurtt's recording session at Studio A, Dearborn Heights, Detroit, where they contributed their performances to "The Soulful Tale of Two Cities" project. The double-album sleeve notes read: "Motown's legendary Funk Brothers and members of Philadelphia's world renowned MFSB take you 'back in the day' with an album filled with classic Philly and Motown hits." Bob Babbitt, Joe Hunter, Uriel Jones, and Eddie Willis performed alongside other notable Detroit session musicians, like Ray Monette, Robert Jones, Spider Webb, and Treaty Womack. The musicians played on the Philly hits, giving their unique Detroit interpretations of the songs under the leadership of Phil Hurtt, Bobby Eli, Clay McMurray and Lamont Dozier. Many other ex-Motown and Detroit artists performed vocals on the session, including the Velvelettes, Carolyn Crawford, Lamont Dozier, Bobby Taylor, Kim Weston, Freda Payne, and George Clinton. In 2008 Uriel Jones, Ray Monette, Dennis Coffey, Robert Jones and Bob Babbitt accompanied other notable Detroit session musicians, including Larry Fratangelo, Dennis Sheridan, Edward Gooch, John Trudell, saxophonist George Benson, Mark Burger, David Jennings, Spider Webb, and Rob Pipho, on the Carl Dixon Bandtraxs project, which featured a Dennis Coffey-Carl Dixon production of four new songs. Vocal performances by Spyder Turner, Pree and Gayle Butts provided lead and backing for the session. The session was arranged by ex-Motown arranger David J. Van De Pitte. The session was also at Studio A, Dearborn Heights, Detroit, and was the dream of a 19-year-old Dixon, back in 1974, to pay homage to musicians, particularly the Funk Brothers, producers and those who influenced him with their music. It took Dixon almost 33 years to find the musicians and meet some of them on the web site soulfuldetroit.com. It was via this web site that he and Dennis Coffey hooked up and then eventually collaborated to make the session work. In 2008 surviving members recorded Live in Orlando, an album and video. In 2010, surviving members of the Funk Brothers accompanied Phil Collins on his Motown covers album, Going Back, and appear in the live Going Back concert DVD.

Background: Ai Weiwei (Chinese: Ai Wei Wei ; pinyin: Ai Weiwei, English pronunciation ; born 28 August 1957 in Beijing) is a Chinese contemporary artist and activist. His father's (Ai Qing) original surname was written Jiang (Jiang ). Ai collaborated with Swiss architects Herzog & de Meuron as the artistic consultant on the Beijing National Stadium for the 2008 Olympics.
Context: On 22 June 2011, the Chinese authorities released Ai from jail after almost three months' detention on charges of tax evasion. Beijing Fa Ke Cultural Development Ltd. (Chinese: Bei Jing Fa Ke Wen Hua Gong Si ), a company Ai controlled, had allegedly evaded taxes and intentionally destroyed accounting documents. State media also reports that Ai was granted bail on account of Ai's "good attitude in confessing his crimes", willingness to pay back taxes, and his chronic illnesses. According to the Chinese Foreign Ministry, he is prohibited from leaving Beijing without permission for one year. Ai's supporters widely viewed his detention as retaliation for his vocal criticism of the government. On 23 June 2011, professor Wang Yujin of China University of Political Science and Law stated that the release of Ai on bail shows that the Chinese government could not find any solid evidence of Ai's alleged "economic crime". On 24 June 2011, Ai told a Radio Free Asia reporter that he was thankful for the support of the Hong Kong public, and praised Hong Kong's conscious society. Ai also mentioned that his detention by the Chinese regime was hellish (Chinese: Jiu Si Yi Sheng ), and stressed that he is forbidden to say too much to reporters. After his release, his sister gave some details about his detention condition to the press, explaining that he was subjected to a kind of psychological torture: he was detained in a tiny room with constant light, and two guards were set very close to him at all times, and watched him constantly. In November, Chinese authorities were again investigating Ai and his associates, this time under the charge of spreading pornography. Lu was subsequently questioned by police, and released after several hours though the exact charges remain unclear. In January 2012, in its International Review issue Art in America magazine featured an interview with Ai Weiwei at his home in China. J.J. Camille (the pen name of a Chinese-born writer living in New York), "neither a journalist nor an activist but simply an art lover who wanted to talk to him" had travelled to Beijing the previous September to conduct the interview and to write about his visit to "China's most famous dissident artist" for the magazine. On 21 June 2012, Ai's bail was lifted. Although he is allowed to leave Beijing, the police informed him that he is still prohibited from traveling to other countries because he is "suspected of other crimes," including pornography, bigamy and illicit exchange of foreign currency. Until 2015, he remained under heavy surveillance and restrictions of movement, but continues to criticize through his work. In July 2015, he was given a passport and may travel abroad.
