Child Rebel Soldier, shortened CRS, is a hip hop supergroup composed of hip hop artists Kanye West, Lupe Fiasco, and Pharrell Williams.

Child Rebel Soldier was conceived with the conception of the song "Us Placers", which appears on Kanye West's Can't Tell Me Nothing mixtape, released just prior to his third studio album Graduation.Lupe Fiasco had produced the song in an attempt to construct a mashup mixtape containing hip hop remakes of alternative rock singer Thom Yorke's solo album, The Eraser coupled with a few Radiohead songs. He originally wanted Kanye West and English rapper The Streets to appear on the mixtape's first song "Us Placers", but Skinner failed to respond while West sent the song over to Pharrell Williams after laying down a verse. After finishing the collaboration, the trio decided to form a group, named by Pharrell as "Child Rebel Soldier". Their first song, "Us Placers", was listed at #43 on Rolling Stone's list of the 100 Best Songs of 2007.

In an 2007 interview with Billboard, Lupe elaborated that the three had hopes to find time to construct a full-length studio album, saying, "Now [our labels are] working it out. Whoever is going to pay is going to pay a whole hell of a lot. Everybody is excited, [but] 'Us Placers' is the only record we have".

Wasalu Muhammad Jaco (born February 16, 1982), better known by his stage name Lupe Fiasco ( /ˈluːpeɪ/ LOO-pay), is an American rapper, record producer, and entrepreneur. He rose to fame in 2006 following the success of his debut album, Lupe Fiasco's Food & Liquor. He also performs as the frontman of rock band Japanese Cartoon under his real name. As an entrepreneur, Fiasco is the chief executive officer of 1st and 15th Entertainment.

Raised in Chicago, Fiasco developed an interest in hip hop after initially disliking the genre for its use of vulgarity. After adopting the name Lupe Fiasco and recording songs in his father's basement, 19-year-old Fiasco joined a group called Da Pak. The group disbanded shortly after its inception, and Fiasco soon met rapper Jay-Z who helped him sign a record deal with Atlantic Records. In 2006, Fiasco released his debut album Lupe Fiasco's Food & Liquor on the label, which received three Grammy nominations. He released his second album, Lupe Fiasco's The Cool, in December 2007. The lead single "Superstar" peaked at number 10 on the Billboard Hot 100. He released Lasers on March 8, 2011 after a two-year delay. The album's lead single "The Show Goes On" peaked at number 9 on the chart, thus becoming his most successful single since "Superstar".

He mainly plays guitar and piano, but has also played drums and bass guitar (notably during the Kid A and Amnesiac sessions). In July 2006, he released his debut solo album, The Eraser.

Yorke has been cited among the most influential figures in the music industry; in 2002, Q Magazine named Yorke the 6th most powerful figure in music, and Radiohead were ranked #73 in Rolling Stone's "100 Greatest Artists of All Time" in 2005.

Yorke was born on 7 October 1968, in Wellingborough, Northamptonshire. At birth, his left eye was fixed shut; the doctors determined that the eye was paralyzed and that the condition was permanent. Yorke's parents took him to an eye specialist, who suggested a muscle graft. Yorke underwent five eye operations before he was six years old. Yorke's father, a chemical equipment salesman, was hired by a firm in Scotland shortly after his son's birth and the family lived there until Yorke was seven. During this time Yorke had to wear a patch over his eye. He has stated that the last surgery was "botched", giving him a drooping eyelid.
