Question:
Public Enemy is an American hip hop group consisting of Chuck D, Flavor Flav, Professor Griff, Khari Wynn, DJ Lord, and the S1W group. Founding member DJ Terminator X left the group in 1999. Formed on Long Island, New York, in 1986, they are known for their politically charged music and criticism of the American media, with an active interest in the frustrations and concerns of the African American community. Their first four albums during the late 1980s and early 1990s were all certified either gold or platinum and were, according to music critic Robert Hilburn in 1998, "the most acclaimed body of work ever by a hip hop act".
Their debut album, Yo! Bum Rush the Show, was released in 1987 to critical acclaim. The album was the group's first step toward stardom. In October 1987, music critic Simon Reynolds dubbed Public Enemy "a superlative rock band". They released their second album It Takes a Nation of Millions to Hold Us Back in 1988, which performed better in the charts than their previous release, and included the hit single "Don't Believe the Hype" in addition to "Bring the Noise". Nation of Millions... was the first hip hop album to be voted album of the year in The Village Voice's influential Pazz & Jop critics' poll.  In 1989, the group returned to the studio to record Fear of a Black Planet, which continued their politically charged themes. The album was supposed to be released in late 1989, but was pushed back to April 1990. It was the most successful of any of their albums and, in 2005, was selected for preservation in the Library of Congress. It included the singles "Welcome To The Terrordome", "911 Is a Joke", which criticized emergency response units for taking longer to arrive at emergencies in the black community than those in the white community, and "Fight the Power". "Fight the Power" is regarded as one of the most popular and influential songs in hip hop history. It was the theme song of Spike Lee's Do the Right Thing.  The group's next release, Apocalypse '91...The Enemy Strikes Black, continued this trend, with songs like "Can't Truss It", which addressed the history of slavery and how the black community can fight back against oppression; "I Don't Wanna be Called Yo Nigga", a track that takes issue with the use of the word nigga outside of its original derogatory context. The album also included the controversial song and video "By the Time I Get to Arizona", which chronicled the black community's frustration that some US states did not recognize Martin Luther King Jr.'s birthday as a national holiday. The video featured members of Public Enemy taking out their frustrations on politicians in the states not recognizing the holiday. In 1992, the group was one of the first rap acts to perform at the Reading Festival, in England, headlining the second day of the three-day festival.
