Background: Ryuichi Sakamoto (Ban Ben Long Yi , Sakamoto Ryuichi, born January 17, 1952) (Japanese pronunciation: [sakamoto rjW:itci]) is a Japanese musician, singer, composer, record producer, activist, writer, actor and dancer, based in Tokyo and New York. He began his career while at university in the 1970s, as a session musician, producer, and arranger.
Context: Sakamoto's production credits represent a prolific career in this role. In 1983, he produced Mari Iijima's debut album Rose, the same year that the Yellow Magic Orchestra was disbanded. Sakamoto subsequently worked with artists such as Thomas Dolby; Aztec Camera, on the Dreamland (1993) album; and Imai Miki, co-producing her 1994 album A Place In The Sun. Roddy Frame, who worked with Sakamoto as a member of Aztec Camera, explained in a 1993 interview preceding the release of Dreamland that he had had to wait a lengthy period of time before he was able to work with Sakamoto, who wrote two soundtracks, a solo album and the music for the opening ceremony at the Barcelona Olympics, prior to working with Frame over four weeks in a New York studio. Frame said that he was impressed by the work of YMO and the Merry Christmas Mr Lawrence soundtrack, explaining: "That's where you realise that the atmosphere around his compositions is actually in the writing - it's got nothing to do with synthesisers." Frame's decision to ask Sakamoto was finalized after he saw his performance at the Japan Festival that was held in London, United Kingdom. Of his experience recording with Sakamoto, Frame said: He's got this reputation as a boffin, a professor of music who sits in front of a computer screen. But he's more intuitive than that, and he's always trying to corrupt what he knows. Halfway through the day in the studio, he will stop and play some hip hop or some house for 10 minutes, and then go back to what he was doing. He's always trying to trip himself up like that, and to discover new things. Just before we worked together he'd been out in Borneo, I think, with a DAT machine, looking for new sounds.
Question: Why else is that reputation not deserved?
Answer: Halfway through the day in the studio, he will stop and play some hip hop or some house for 10 minutes,

Background: 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".
Context: Carlton Ridenhour (Chuck D) and William Drayton (Flavor Flav) met at Long Island's Adelphi University in the mid-1980s. Developing his talents as an MC with Flav while delivering furniture for his father's business, Chuck D and Spectrum City, as the group was called, released the record "Check Out the Radio", backed by "Lies", a social commentary--both of which would influence RUSH Productions' Run-D.M.C. and Beastie Boys. Chuck D put out a tape to promote WBAU (the radio station where he was working at the time) and to fend off a local MC who wanted to battle him. He called the tape Public Enemy #1 because he felt like he was being persecuted by people in the local scene. This was the first reference to the notion of a public enemy in any of Chuck D's songs. The single was created by Chuck D with a contribution by Flavor Flav, though this was before the group Public Enemy was officially assembled. Around 1986, Bill Stephney, the former Program Director at WBAU, was approached by Ali Hafezi and offered a position with the label. Stephney accepted, and his first assignment was to help fledgling producer Rick Rubin sign Chuck D, whose song "Public Enemy Number One" Rubin had heard from Andre "Doctor Dre" Brown. According to the book The History of Rap Music by Cookie Lommel, "Stephney thought it was time to mesh the hard-hitting style of Run DMC with politics that addressed black youth. Chuck recruited Spectrum City, which included Hank Shocklee, his brother Keith Shocklee, and Eric "Vietnam" Sadler, collectively known as the Bomb Squad, to be his production team and added another Spectrum City partner, Professor Griff, to become the group's Minister of Information. With the addition of Flavor Flav and another local mobile DJ named Terminator X, the group Public Enemy was born." According to Chuck, The S1W, which stands for Security of the First World, "represents that the black man can be just as intelligent as he is strong. It stands for the fact that we're not third-world people, we're first-world people; we're the original people." Hank Shocklee came up with the name Public Enemy based on "underdog love and their developing politics" and the idea from Def Jam staffer Bill Stephney following the Howard Beach racial incident, Bernhard Goetz, and the death of Michael Stewart: "The Black man is definitely the public enemy." Public Enemy started out as opening act for the Beastie Boys during the latter's Licensed to Ill popularity, and in 1987 released their debut album Yo! Bum Rush the Show.
Question: When did they first perform as Public Enemy?
Answer:
With the addition of Flavor Flav and another local mobile DJ named Terminator X, the group Public Enemy was born.
